Is the heart rate fast in winter or in summer?
2, the summer weather is hot, the human body's metabolism is strong, and the heartbeat will accelerate, which is generally normal at around 70/ minute. If patients have psychological abnormalities, they should go to the hospital as soon as possible to carry out the system, but it is normal for elderly people such as laborers or athletes with heavy physical strength to have psychological changes.
Extended data
Heart rate refers to the number of heart beats in one minute.
Heart rate, bpm (beats per minute), refers to the number of beats per minute. Under normal circumstances, the heart beats regularly within a certain frequency range. This impulse of heart beating comes from sinoatrial node and is transmitted to atrium and ventricle in a certain order and rate, which coordinates the synchronous contraction and relaxation of all parts of the heart and forms a heartbeat, which is a normal rhythm. Because it originated from sinus node, it is called sinus rhythm. The ECG characteristics of sinus rhythm are: P wave appears regularly, and the P wave morphology shows that the excitement comes from sinus node (that is, P wave stands upright in Ⅰ, Ⅱ, aVF and V4-V6, and aVR is inverted).
The frequency of normal sinus P wave is generally 60 ~ 100 times/minute. When the heart rhythm is sinus rhythm, but the frequency is less than 60 beats/min, it is called sinus bradycardia. When the heart rhythm is sinus rhythm, but the frequency is higher than 100 beats/min, it is called sinus tachycardia. Some special people, such as athletes, young people and the elderly, have bradycardia, but it will not affect the body and does not need intervention; Moreover, pregnant women, especially in the middle and late pregnancy, will also have tachycardia and will return to normal after delivery.
