How is dizziness, chest tightness and dyspnea? I sometimes feel it when the weather is sultry.

Chest tightness and shortness of breath are subjective symptoms of dyspnea. Chest tightness caused by organic reasons: 1. Cardiogenic chest tightness-chest tightness after fatigue and dyspnea, or paroxysmal dyspnea at night, which patients can hold during sleep, and can be seen in heart patients with pulmonary congestion and cardiac insufficiency. Chest tightness can also be the manifestation of angina pectoris during myocardial ischemia of coronary heart disease. Young people should pay attention to the possibility of myocarditis. Second, pulmonary chest tightness-seen in bronchial asthma, pleural effusion, spontaneous pneumothorax, pulmonary fibrosis and so on. Chest tightness caused by nervous function-common in cardiovascular dysfunction. Patients feel chest tightness, shortness of breath, subjective lack of air, poor breathing, often sigh-like breathing, and feel comfortable after breathing; It is often accompanied by palpitations, tingling in the precordial area, and nervous system symptoms such as fatigue, dizziness, confusion, panic, anxiety, sweating and insomnia. The disease is mostly young women, showing various symptoms, similar to coronary heart disease and angina pectoris, but no organic lesions were found in ECG and B-ultrasound. In addition, organic chest tightness mostly occurs after exercise or fatigue, and functional chest tightness mostly occurs at rest; After sitting up, the organic chest tightness can be obviously improved, while the functional chest tightness often does not change because of the change of posture. The pathogenesis of the disease is autonomic nervous dysfunction and increased sympathetic nerve tension, which causes a series of functional symptoms and manifestations of cardiovascular system. When you have obvious symptoms of chest tightness and shortness of breath, you should do chest X-ray, electrocardiogram, echocardiography or myocardial enzyme examination, and first rule out pathological and organic diseases such as heart and lung. If no abnormalities are found in the examination, most of them are neurological symptoms, so don't worry too much. After mental conditioning, physical enhancement, or necessary rest and medication, you will gradually get better and recover.
