Coronary heart disease is related to exertion, emotional excitement, etc. If it is angina, rest or nitroglycerin containing can be relieved. Cardiac enzymes, troponin, electrocardiogram, echocardiogram, coronary CT, cardiac MRI or angiography can be used to clearly exclude cardiovascular problems. 2, arrhythmia: When arrhythmia occurs, such as atrial fibrillation, atrial flutter, frequent premature beats, ventricular tachycardia, etc. affect the effective contraction of the heart muscle, which can lead to a reduction in cardiac output and insufficient blood supply to the heart muscle, causing heart congestion and heart pain and feeling blocked in the chest. 3, gastroesophageal reflux disease: gastroesophageal reflux disease occurs when the reflux stimulates the esophagus, can cause chest pain, sometimes similar to angina pectoris. It can be accompanied by reflux and heartburn sensation.
