Signal 1: Chest pressure rises after exercise. The feeling of chest pressure is chest tightness, which will be aggravated after exercise and emotional excitement. Boredom mainly represents insufficient blood supply to the heart-there is something wrong with the coronary artery that supplies blood to the heart, and severe chest tightness is a sign of coronary heart disease. If the chest tightness is relieved after exercise, don't worry, because the chest tightness of coronary heart disease will not be relieved after exercise. In addition, if you feel chest tightness during running, you should see a doctor as soon as possible, and don't think that rest is enough.
Signal 2: palpitation and palpitation. Palpitation and palpitation when excited or tired-these are common symptoms of arrhythmia. Ordinary people are very tired and have palpitations, but they are not very uncomfortable. When running a marathon, people are under pressure. Cardiac arrest can lead to sudden death, which is the cause of sudden death caused by arrhythmia. However, the malignant consequences caused by arrhythmia are few, and most of them are organic heart diseases.
Signal 3: Congenital, no obvious symptoms. Some people have congenital structural problems in their hearts. Most of them have no symptoms in the early stage and don't feel uncomfortable at ordinary times. What should I do? If you are worried about accidents, especially those who want to run a marathon, I suggest you see a doctor for auscultation. Color Doppler echocardiography can be performed when necessary. If you have problems, you can do daily exercise instead of running a marathon.
