In summer, I feel chest tightness, shortness of breath and poor breathing. How is sighing breathing?

Chest tightness and shortness of breath is a feeling of conscious chest tightness and poor breathing, which may be caused by neurological dysfunction, that is, the function of the heart and lungs is out of regulation, and there is no obvious organic disease diagnosed by western medicine; Severe cases are caused by heart and lung diseases, which can be caused by coronary heart disease, myocardial blood supply insufficiency, chronic bronchitis, emphysema, pulmonary heart disease, etc., and there are obvious organic lesions diagnosed by western medicine. For physicians, "chest tightness and shortness of breath" can be light or heavy, and minor general diseases, such as gastroesophageal reflux and respiratory infection; Serious and potentially fatal diseases, such as myocardial infarction, angina pectoris, aortic dissection, pulmonary embolism, pneumothorax, upper digestive tract rupture, etc. The diagnosis of these diseases can be initially distinguished by detailed medical history, but the final diagnosis can still be made with the help of western medicine, so we must be extra cautious in clinic.
