Whether to take medicine for arrhythmia, and what kind of medicine to take, depends on different situations. For some arrhythmias, it is unnecessary to take medicine, such as incidental atrial premature beats, incidental ventricular premature beats, etc; But for some arrhythmias, such as rapid atrial fibrillation, drugs such as receptor blocker, calcium channel blocker and amiodarone can be given to control heart rate. For frequent ventricular premature beats based on heart failure, it is best to treat them with a receptor blocker. So what kind of medicine to use for arrhythmia should be judged by the specialist.
