Sometimes the heart will suddenly beat violently for several reasons. 1. Consider physiological. The heart may beat violently after strenuous activities, such as running, fast walking, climbing hills and stairs, or when the patient is angry or has a large mood swing. In this case, the symptoms will be relieved after rest. 2. Consider it pathological. Most often seen in underlying heart disease, such as coronary artery disease, arrhythmia, cardiomyopathy, heart valve disease, when the heart will appear to be beating hard. At this point we need to check a 24-hour ambulatory ECG to identify the specific cause and see if it is organic or functional. If it is organic, it needs to be treated with symptomatic medication. In addition, if the heart disease is organic, in addition to a pounding heart, it will be accompanied by heart-related symptoms such as pain in the precordial region, chest tightness, and shortness of breath.
