A strong beating in the chest is a conscious symptom, and there are two kinds of cases. One is a physiological condition, for example, a strong heartbeat occurs when a person is strenuously active or angry, which is a normal phenomenon and is a compensatory response of the heart to the increased load. Another condition is pathological, for example, if a patient has a strong chest beat in a state of quiet rest, in this case, a visit to the cardiovascular medicine department is required. The doctor will perform the necessary physical examination, such as auscultation, to have a general judgment of the possible cause of the disease. The doctor may prescribe an electrocardiogram, a twenty-four-hour ECG, and other tests to rule out the presence of arrhythmias. If arrhythmias are present what kind of arrhythmias are present, etc., including whether there are premature beats, atrial fibrillation, etc. If the diagnosis is still not clear, the doctor may recommend that the patient be hospitalized for further examination and treatment.
