What is the reason why the heart often beats fast?
1. Common causes of rapid heartbeat
The etiology of sinus tachycardia is mostly functional, and it can also be seen in organic heart disease and extracardiac factors. Its production is mainly related to sympathetic nerve excitation and decreased vagus nerve tension.
(1) Physiology: Physiological sinus tachycardia is very common. There are many factors that affect the heart rate, such as * * * changes, physical activity, food digestion, emotional anxiety, pregnancy, excitement, fear, excitement, drinking, smoking and drinking tea, which can all accelerate the heart rate. In addition, age is also a factor, and children's heart rate tends to be faster.
(2) Pharmacology: such as sympathomimetic drugs such as ephedrine and adrenaline. Parasympathetic nerve blocking drugs such as atropine, caffeine, thyroxine and amphetamine can cause tachycardia.
(3) Pathology: Systemic diseases such as high fever, anemia, hypoxia, infection, hyperthyroidism, pain, acute rheumatic fever, beriberi and neurosis can all cause tachycardia.
(4) Cardiovascular diseases: Acute blood loss, hypotension and shock, arteriovenous fistula, heart failure, myocarditis, cardiomyopathy, pericarditis, acute myocardial infarction and various organic heart diseases can all lead to sinus tachycardia.
Two? As for the harm: when the pathological tachycardia occurs, the patient suddenly feels flustered and his heart rate increases.
It lasts for a few minutes, hours to days, and then suddenly returns to normal heart rate. During the attack, the patient felt palpitation, chest tightness, precordial discomfort, head and neck swelling and jumping. People without heart disease generally have no obvious effect, but the attack time is long. When the heart rate exceeds 200 beats per minute, patients will appear blackness, dizziness, fatigue, nausea and vomiting due to the drop of blood pressure, and even suddenly faint, shock or heart failure and pulmonary edema. Three? What should I pay attention to if my heart rate is too fast? (1) Patients with tachycardia must pay attention to their overall physique.
Improve and actively participate in qigong exercise.
(2) Open-minded, optimistic and cheerful, be steady and steady when encountering difficulties, and don't be irritable.
(3) If it is not tachycardia caused by organic heart disease, and I have no obvious pain, I don't need to rely on drugs.
(4) You can stop heavy physical or high-intensity work during the attack and have a rest to recover your physical strength.
(5) Avoid spicy and hot food, such as ginger, pepper, alcohol, tobacco, curry, coffee, chocolate and strong tea.
Eat more foods that nourish yin and blood, calm the heart and soothe the nerves, such as animal liver and kidney, soft-shelled turtle, soft-shelled turtle, black and white fungus, lotus seeds, walnuts, longan, honey, lily, mulberry and so on.
(6) Don't watch nervous movies and take part in intense entertainment activities.
(7) Live a regular life, go to bed early and get up early, and don't stay up late, so that the body's biological clock can conform to the natural rhythm.
Question 2: What is the reason for the rapid heartbeat?
In adults, when the rhythm controlled by sinus node exceeds 100 beats per minute, it is called sinus tachycardia. This is the most common tachycardia, and its occurrence is often related to sympathetic excitation and decreased vagal tension.
Physiologically, it can be caused by exercise, anxiety and emotional excitement, or after the application of drugs such as adrenaline and isoproterenol.
It is easy to occur in heart diseases such as fever, hypovolemia, anemia, hyperthyroidism, respiratory insufficiency, hypoxemia, hypokalemia and heart failure.
The disease can be cured after controlling the primary disease or inducing factors, but it is easy to recur.
Guiding opinions:
（ 1）
① Function: Reserpine can increase the release of sympathetic nerve medium (norepinephrine) in the vesicles of sympathetic nerve endings, and prevent the sympathetic nerve medium from entering the vesicles, so the medium in the vesicles is gradually reduced or exhausted, thus hindering the conduction of sympathetic nerve impulses and slowing down the heart rate.
② Administration and dosage: 0. 1.25 ~ 0.25 mg orally, 2 ~ 3 times a day.
② Feel at ease
① Function: Propranolol is a β -receptor blocker, which can block the β -receptor of myocardium, so it can slow down the heart rate.
Administration and dosage: take orally 5 ~ 10 mg, three times a day.
③ Verapamil
Function: It can inhibit the autonomy of sinus node and atrioventricular junction, prolong the conduction of atrioventricular node (A-H interval) and slow down the heart rate.
Administration and dosage: 40 ~ 80 mg orally, three times a day.
In addition, sedatives can be used in combination.
Second, the treatment of sinus tachycardia prescription
Prescription: 30g of polygala tenuifolia, 0/5g of Bupleurum root/kloc-,0/5g of keel/kloc-,30g of poria cocos, 20g of atractylodes macrocephala, and 0g of gardenia/kloc-. Usage: daily 1 dose, decocted in water for 3 times. The dose of 5 ~ 10 is 1 course of treatment.
Disease analysis:
Arrhythmia refers to the beating of the heart rate that is not within the normal range. The heart rate is 160 ~ 220 beats/min, which is often called paroxysmal tachycardia. Heart rate below 60 beats/min (generally higher than 40 beats/min) is called sinus bradycardia. Heart rate below 60 beats/min (generally higher than 40 beats/min) is called sinus bradycardia.
Guiding opinions:
1. Sinus bradycardia, if the heart rate is not less than 50 beats per minute, if there are no symptoms, no treatment is needed.
2. If the heart rate is less than 40 beats per minute and symptoms appear, drugs (such as atropine, ephedrine or isoproterenol) can be used to increase the heart rate.
3. Patients with sinus bradycardia accompanied by sinus arrest and syncope may consider installing artificial pacemakers.
4. Treatment of primary disease.
5. Symptomatic support treatment.
Disease analysis:
54-year-old, his heart rate suddenly increased with chest pain.
Guiding opinions:
I suggest you go to the hospital for an electrocardiogram. Paroxysmal tachycardia is currently considered.
Disease analysis:
Heart rate 180, obviously too fast. Many reasons can lead to excessive heart rate, such as angina pectoris, arrhythmia and acute myocardial infarction. All these can cause chest pain and the treatment methods are different.
Guiding opinions:
There are many reasons for tachycardia, such as angina pectoris, acute myocardial infarction and arrhythmia, and there are many types of arrhythmia, such as sinus arrhythmia, sinus tachycardia, ventricular tachycardia and supraventricular tachycardia. There are many. If you have angina pectoris, you can treat it with nitroglycerin, that is, quick-acting pills, weak myocardial infarction and arrhythmia, and go to the hospital for regular treatment.
Disease analysis:
(1) Patients with tachycardia must pay attention to the improvement of their overall physique and actively participate in Qigong exercise.
(2) Open-minded, optimistic and cheerful, and be steady and not impatient when dealing with difficulties.
(3) If it is not tachycardia caused by organic heart disease, and I have no obvious pain, I don't need to rely on drugs.
When you have an attack, you can stop heavy physical or high-intensity work and take a break to recover.
(4) avoid sexual intercourse, in order to improve * * * and restrain the heart fire.
(5) Avoid spicy and hot food, such as ginger, pepper, alcohol, tobacco, curry, coffee, chocolate and strong tea.
Guiding opinions:
Eat foods that nourish yin and blood, calm the heart and soothe the nerves, such as animal liver and kidney, soft-shelled turtle, soft-shelled turtle, black and white wood, etc ... ";
Question 3: What causes high heart rate? I don't know how fast you are ... Paroxysmal supraventricular tachycardia is a common arrhythmia, which is a series of clinical manifestations caused by sudden increase of heartbeat. This disease is very common in people without organic heart disease, with more young people than old people and slightly more women than men. It has been proved that paroxysmal supraventricular tachycardia is related to some kind of congenital structural abnormality of the heart, and this small structural change can not be found without special examination in most cases. First, the symptoms of patients in a calm state, without any warning, the heartbeat suddenly accelerated, the pulse is mostly 160 ~ 240 beats/min, while the children can reach 300 beats/min. This heartbeat suddenly returned to normal. The duration of the attack varies from a few seconds to a few days. Most patients can stop after onset, and a few patients can stop after taking medicine. Other symptoms vary in severity, from palpitation, asthma, dizziness and fatigue to chest pain, dyspnea, syncope, spasm or shock. The severity of symptoms depends on the heart rate at the time of attack, whether there are other heart diseases and the patient's tolerance. Second, the diagnosis method ECG can make a diagnosis at the time of onset. When the disease does not occur, the electrocardiogram may be normal. Go to the hospital for induction test and make ECG diagnosis after induction. Some patients have preexcitation syndrome or short PR sign before onset, which is helpful for diagnosis. Electrocardiogram is preexcitation syndrome or short PR sign, but those who don't get sick don't need treatment. Third, the treatment of 1 Simple treatment at the onset: gently press the eyeball or carotid sinus with your fingers and use chopsticks to cause nausea (this method is recommended for non-medical workers), and some patients can use this method to stop the attack. 2. Drug treatment and prevention: Some drugs can stop paroxysmal supraventricular tachycardia and prevent its attack, but they cannot be cured, and long-term medication may have side effects. 3. Catheter surgery: At present, the best choice is radiofrequency ablation. Radiofrequency ablation is to puncture the femoral vein, femoral artery or subclavian vein and insert the electrode catheter into the heart under the monitoring of X-ray angiography. Firstly, the position of the abnormal structure causing tachycardia is checked and determined, and then the high-frequency current of 100 kHz ~ 1 and 5MHz is locally released at this position, resulting in a very high temperature in a small range, and the water in the local tissue is evaporated by thermal efficiency. Compared with drug therapy, radiofrequency ablation is not a temporary prevention or termination of tachycardia, but a one-time radical treatment without antiarrhythmic drugs. Compared with surgery, it does not need thoracotomy and general anesthesia, and the patient has no pain and the operation method is simple. In a word, this is a safe, effective and simple treatment. Fourth, pay attention to the fact that you can't engage in special occupations before the disease is cured, such as driving and diving. , in order to avoid sudden onset of unexpected circumstances. Holding your breath can be recovered in a short time, but you can't pay attention to and prevent the attack (I am a cardiologist). Paroxysmal supraventricular tachycardia (cardiovascular medicine) is a common tachyarrhythmia caused by reentry movement in clinic. It is characterized by paroxysmal sudden attack and sudden stop, and the heart rate is generally 160-220 beats/min. Each attack can last less than 1 sec or seconds, minutes, hours or even days, and can be terminated automatically or after treatment. Some attacks can be repeated. The attack interval is similar to that of normal people, and tachycardia can be terminated by vagus nerve, drugs, synchronous direct current or transesophageal tachycardia. At present, the most effective and thorough treatment is radiofrequency ablation. The clinical manifestation is 1. The onset and termination are often sudden, and the inducement is mostly emotional excitement, sudden change of * * *, sudden exertion, fatigue or full meal, and sometimes there is no inducement. 2. There are many palpitations, chest tightness, head and neck swelling and fatigue. Some may have sweating, polyuria, vomiting, numbness of limbs, etc. Sometimes accompanied by fear. Shock, seizures (Asperger's syndrome), angina pectoris and acute heart failure. 3. Few people can have a fast and regular heart rhythm, and most people's heart rate is 160-220 beats/min. The intensity of the first heart sound is constant, and the pulse is thin and fast. The diagnosis is based on 1. The heart rate during the attack was 160-220 beats/min. The heart rhythm is regular and lasts for several seconds to several days. It is not influenced by * * *, exercise or emotional excitement. 2. ECG shows that the heart rate is 160-220 beats/min, and the R-R interval is regular or basic; QRS complex morphology and normal sinus rhythm.
Question 4: What is the fast heartbeat? Young people don't have to be nervous about tachycardia.
As we all know, the heart is an important organ of the human body. It is located in the left part of the middle part of the chest, with sternum and ribs in front and esophagus and spine in the back. It's about as big as your fist.
In a person's life, the heart always works without sleep, and it will stop beating until the end of life. Because the heart is constantly contracting and relaxing, the blood in the blood vessels can flow continuously and people can survive. When the heart beats, the apex hits the chest wall, forming a beating apex near the left side of the heart. People with thin bodies and thin chest walls can clearly see or touch the beating of the heart.
Under normal circumstances, the heartbeat of adults is between 60 and 80 beats per minute, but in a quiet state, if the heartbeat exceeds 100 beats per minute, it is called "tachycardia", also known as "palpitation".
"Tachycardia" is not a disease name, but a symptom. The causes of tachycardia vary widely, the most common is the heart itself, such as various types of heart disease, myocarditis, heart failure and so on. Suffering from systemic diseases such as anemia, fever, acute and chronic infection, shock, hyperthyroidism and gas poisoning can also lead to tachycardia. When normal people are exercising or emotional, they take strong liquor, strong tea, strong coffee or smoke more, and take some drugs. , can speed up their heartbeat.
Why shouldn't young people be nervous about tachycardia?
Because the most common cause of tachycardia in young people is functional autonomic nervous disorder, which has been confirmed by more and more clinical cases and cardiologists.
Most young men and women with palpitations were very nervous when they came to see a doctor, but after auscultation and general examination of related items, they found that all the tests were normal except tachycardia. In addition to feeling flustered, patients often have neurasthenia symptoms such as dizziness, fatigue, insomnia and dreaminess.
Tachycardia is common among young people. According to the statistics of clinical data, it accounts for 65,438+06.8% of all young people, and is clinically called "adolescent tachycardia".
So, why are adolescent autonomic nerves disordered?
Because adolescence is a transitional stage from basic maturity to full maturity. During this period, teenagers' bodies and various important organs such as heart, lungs, brain and genitals are changing rapidly, and all these changes are dominated by nervous system and endocrine system.
In the nervous system, there is an autonomic nerve whose center is not in the cerebral cortex, but in the hypothalamus under the cortex, so it is not controlled by human will. It goes without saying that autonomic nerve regulates the coordination and balance of sympathetic nerve and vagus nerve to adapt to the changes of external environment.
However, the autonomic nervous function in adolescence is generally unstable and prone to disorder or dysfunction. Tachycardia is due to the coordination disorder between sympathetic nerve (accelerating the heart) and vagus nerve (inhibiting the heart) under the command of autonomic nerve, and sympathetic nerve is dominant. In other words, the occurrence of tachycardia is mainly related to the decrease of vagus nerve tension and sympathetic nerve excitation. However, this is only a temporary obstacle and does not require special treatment. After puberty, palpitations will heal themselves.
Although juvenile tachycardia is not an organic disease, it will be very uncomfortable when the heart rate is accelerated, especially when the heart rate exceeds 140 beats per minute. Therefore, when tachycardia exceeds 120 times per minute, you should take a proper rest and take some drugs to adjust the autonomic nerve balance. 120 times or less generally do not need to rest, just use some medicine appropriately.
In a word, young people should treat tachycardia correctly with an optimistic attitude of "being frank and carefree" and should not be burdened with thoughts for temporary puberty obstacles. They should study and work with full spirit, and take part in various social activities and physical exercises. Practice has proved that proper activities and exercises can often relieve symptoms. Smoking, excessive drinking or drinking strong tea, coffee, etc. It often makes your heart beat faster, so you should quit smoking and drinking, be happy and live a regular life. This is the only way to cure tachycardia.
Question 5: Why does the girl's heart beat fast? Under normal circumstances, the heart rate of adults should be between 60 and 80 beats per minute. Of course, this means that in a quiet state, if a person's heartbeat exceeds 65,438+000 beats per minute in a quiet state, it is palpitation, also known as excessive plastic heartbeat. What is the reason for the fast heartbeat? Rapid heartbeat is not caused by disease, it is a state, and the reasons for this situation vary from person to person, of course, some are pathological.
Causes of rapid heartbeat
1, sinus tachycardia
(1) Physiology: It is common that the heart beats faster due to this reason. There are many factors that affect the heart rate, such as * * * changes, physical activity, food digestion, emotional anxiety, pregnancy, excitement, fear, excitement, drinking, smoking and drinking tea, which will increase the heart rate. In addition, age is also a factor, and children's heart rate tends to be faster.
(2) Pharmacology: Some drugs, such as ephedrine and adrenaline, can cause people's heartbeat to accelerate. Parasympathetic nerve blocking drugs such as atropine, caffeine, thyroxine and amphetamine can cause tachycardia.
(3) Pathology: Some systemic diseases can also cause rapid heartbeat: high fever, anemia, hypoxia, infection, hyperthyroidism, pain, acute rheumatic fever, beriberi and neurosis can all cause tachycardia.
(4) Cardiovascular diseases: Acute blood loss, hypotension and shock, arteriovenous fistula, heart failure, myocarditis, cardiomyopathy, pericarditis, acute myocardial infarction and various organic heart diseases can all lead to sinus tachycardia.
2. Paroxysmal heartbeat is very fast
(1) Paroxysmal supraventricular tachycardia. Generally speaking, this phenomenon is common in people without heart disease, and can also be seen in rheumatic heart disease, hyperthyroidism, coronary heart disease, hypertensive heart disease, preexcitation syndrome and so on. The heart rate is below 200 beats per minute, and the attack time is short.
② Paroxysmal ventricular tachycardia. This situation is also caused by some diseases. Ventricular tachycardia mostly includes severe and extensive cardiomyopathy, severe hypertension, rheumatic heart disease and coronary heart disease complicated with myocardial infarction. During the attack, the heart rate is mostly 150-250 beats/min, and there are often shocks and precordial pain.
Although under normal circumstances, exercise can cause a person's heart to beat faster, if this happens in a quiet state, we need to pay attention to it, understand the reasons and choose appropriate methods to improve it, and pay special attention to daily health care in our lives.
Question 6: My heart often beats faster. What is the reason? I have a heart problem, or I often see girls.
Question 7: What's the harm of a fast heartbeat? We can compare the heart to a house with a power generation system. The human heart can beat continuously because there is a complex current conduction system in the muscle layer of the heart. The heart has a natural pacemaker that provides a conduction rhythm point from the atrium to the ventricle. The transmission of pacemaker causes heartbeat, which can effectively transport blood to all parts of the body. Some people's heart current conduction may have a "short circuit or loop", which is the cause of irregular heartbeat. This irregular heartbeat is called "arrhythmia", and there are various types and reasons for arrhythmia. Most people often have a fast heartbeat or occasionally "miss one or two heartbeats", but for most people, it is not the main sign of abnormal heart structure. Find out how to beat your heart. Many people go to the hospital for help when they have palpitations. When they hung up the phone to see the doctor, their heartbeat returned to normal. In order to get a correct diagnosis, patients need to make some records to help doctors find out the cause. Including seizures, is it sudden or slow? Pulse frequency, irregular? Do you have dizziness, cold sweat, chest tightness and other symptoms? Dr. Ke Qinwen said that in addition to consultation and auscultation, cardiologists will also arrange ordinary electrocardiogram, exercise electrocardiogram and echocardiography according to the condition. For patients with uncertain attack frequency, there are several special diagnostic tools: (Holter monitor): This portable ECG recorder can not only record arrhythmia, but also analyze heart rate variability, which is helpful to evaluate the risk of sudden death. ◆ Event monitors: wrist type, card type, ring type, etc. It's the size of a CD-ROM walkman, which can be worn for days or even weeks, and an abnormal heartbeat can be recorded by pressing the switch immediately after the attack. It is suitable for patients who have no daily attacks or 24-hour ECG abnormalities. ◆ Inclined bed test: Patients lie on a special bed with an inclination of 70 degrees for 20 ~ 40 minutes, and observe the heartbeat frequency and regularity and the changes of blood pressure. It can be used for the diagnosis of neuropsychiatric syncope and the evaluation of curative effect after treatment. ◆ Electrophysiological examination: It is an invasive examination. It is suitable for patients with severe symptoms, high-risk groups, complicated arrhythmia or recurrent attacks. In the cardiac catheterization room, electrodes were placed in the heart through inguinal vessels, and ECG changes and heart rhythm conduction paths in the heart were recorded. When necessary, the heart induces arrhythmia in patients to find out the problem, thus establishing the basis for diagnosis and treatment. How should the method of keeping the heart beating normally treat arrhythmia? Mayo Medical Center pointed out that after evaluation and diagnosis, doctors will decide the treatment plan according to the degree of influence of symptoms on life (such as often fainting without warning) and whether arrhythmia will worsen or lead to other complications. Some arrhythmias do not need treatment. We just need to keep a regular life and rest, relax and be less angry, properly adjust emotions and pressures, and avoid the sources of sympathetic excitement such as cigarettes, alcohol, coffee, cola and tea, which can effectively improve symptoms. When arrhythmia is complicated with hypertension, coronary artery obstruction or heart failure, these cardiovascular problems should be treated together with arrhythmia. There are many antiarrhythmic drugs. Doctors will choose appropriate drugs according to the type of arrhythmia and the cause of heart disease. If you feel uncomfortable taking these drugs, you should inform your doctor immediately, because antiarrhythmic drugs sometimes induce new arrhythmia. For arrhythmia with slow heartbeat, a pacemaker can be installed. It can regulate the heart rate of patients with activities such as sleep, walking and exercise. For arrhythmia with rapid heartbeat, we can first find abnormal conduction path or abnormal discharge focus through cardiac catheter, and then use electrocautery to make the focus lose conduction function and cure it. There is a female patient aged 19 who often hangs up in the emergency department because of chest pain and rapid heartbeat exceeding 150 times per minute. After examination, it was found that her heart had one more conduction circuit than ordinary people, which would lead to arrhythmia. After electrocautery treatment, she got rid of the palpitation that had been entangled for many years. For the most serious and potentially fatal arrhythmias such as ventricular tachycardia and ventricular fibrillation, implantable ventricular defibrillators can be used to save lives. Once the attack occurs, the defibrillator will immediately sense and automatically shock ventricular fibrillation within a few seconds to restore the normal speed and regularity of the heartbeat and prevent the patient from sudden death. In any case, extremely irregular, too fast or too slow heartbeat may cause greater danger to patients. I suggest that if you have these heart rhythm problems, you should have a look.
