Frequent atrial tachycardia can be treated with medications such as metoprolol, verapamil and propafenone according to the specific cause. 1. Metoprolol: Metoprolol is a beta-blocker, which is effective for atrial tachycardia, which is caused by excessive increase of sympathetic excitability in the body. The drug selectively binds to beta-adrenergic receptors, thus causing neurotransmitters and catecholamines to affect the beta-activated receptors, thereby reducing the heart rate. 2. Verapamil: a calcium antagonist. It is effective in atrial tachycardia caused by triggered activity. It can interfere with the process of energy consumption and metabolism of cardiomyocytes, reduce myocardial oxygen demand, and indirectly reduce the load, thus reducing heart rate. 3. Propafenone: It can be used for the prevention and treatment of frequent atrial tachycardia, inhibiting the influx of fast sodium ions and slowing down the rate of depolarization, thus reducing the heart rate. If the symptoms of frequent atrial tachycardia, persistent unrelieved, you need to consult a doctor in a timely manner to comply with medical treatment, the use of drugs must be used in accordance with medical advice.
