Heart shivering is a symptom of self-perceived discomfort in the precordial area, and most patients who are able to experience this symptom have underlying heart disease. During an acute heart attack, the heart feels uncomfortable due to the symptoms of various arrhythmia episodes. For example, in the case of coronary artery disease combined with arrhythmia, irregular heartbeat due to the occurrence of various premature beats can cause the heart to shake, especially when the number of premature beats is relatively high, and it appears and disappears with the appearance of premature beats. Heart shaking can also occur during rapid heart rate disorders, such as rapid atrial fibrillation, atrial flutter, and paroxysmal supraventricular tachycardia. Therefore, once the above symptoms appear, promptly go to the nearest hospital for an electrocardiogram to clarify the electrocardiographic changes occurring in the heart at this time, so that a clear diagnosis can be made and symptomatic treatment can be given.
