Ventricular arrhythmia is an abnormality in the rhythm, frequency, and origin of the heart impulse, which is a cardiovascular disease, or a cardiac electrophysiology disease. Many large tertiary hospitals have many subspecialties for cardiovascular diseases, such as electrophysiology, coronary heart disease, hypertension, etc. Smaller hospitals are not detailed due to the lack of doctors and are unified into cardiovascular medicine. Ventricular arrhythmia is a disease caused by abnormal cardiac electrophysiological activity, so in hospitals with electrophysiology ward, it should be admitted to the electrophysiology ward. Nowadays, specialized treatment is advocated, so in hospitals that are very carefully divided, they are admitted to various subspecialties, and if there is no subspecialty, they are treated in the department in which the disease is divided.
