Chest beating fast with chest tightness and tension may suffer from cardiovascular diseases such as coronary heart disease, pathologic ventricular hypertrophy, arrhythmia, etc., can go to the hospital for further examination. 1. Coronary heart disease: with the degree of coronary atherosclerosis increases, when there is an increase in the amount of exercise, myocardial oxygen consumption increases, there will be a lack of oxygen supply, at this time that will occur fast heartbeat and chest tightness and tension symptoms. Isosorbide nitrate tablets can be used to alleviate the symptoms and timely medical treatment, if necessary, feasible cardiac stenting. 2. Pathological ventricular hypertrophy: hypertensive heart disease, aortic insufficiency, mitral valve insufficiency, etc. caused by left ventricular hypertrophy, myocardial contraction force increase, may appear rapid heartbeat with chest tightness and other symptoms. 3. Arrhythmia: When arrhythmia such as sinus tachycardia, supraventricular tachycardia, atrial fibrillation occurs, it can be accompanied by rapid heartbeat and chest tightness, which should be found out whether it is caused by organic heart disease and actively treated. Therefore, when there is a rapid heartbeat accompanied by chest tightness and tension, it is necessary to go to the hospital in time to avoid delaying the condition.
