Atrial premature beats include atrial premature beats, ventricular premature beats, etc. The treatment drugs include beta-blockers, non-dihydropyridine calcium channel blockers, amiodarone, etc., such as metoprolol, verapamil and amiodarone. 1. β-blockers: common drugs include propranolol, metoprolol and so on. Propranolol can slow down the rate of 4-phase diastolic automatic depolarization, reduce autoregulation, but also slow down the rate of 0-phase depolarization of the action potential, slowing down the conduction velocity. 2. Non-dihydropyridine calcium channel blockers: common drugs include verapamil, which can block L-type calcium channels, reduce sinus node autoregulation, and prolong the effective duration of atrioventricular node. 3. Amiodarone: Amiodarone can inhibit the sodium, potassium and calcium ion channels of cardiomyocytes, which makes the autoregulation and conduction of sinus node decrease. If patients have palpitations, chest tightness, fatigue and other abnormal symptoms, they should go to the hospital in a timely manner, after clarifying the cause of the disease, follow the doctor’s instructions for treatment, do not self-medication, so as not to delay the condition or adverse reactions.
