What medicine should I take if my heart beats too fast? Reasonable use of medicine is the key

There are pathological and physiological causes of tachycardia. It can occur after strenuous exercise, excessive emotions, drinking large amounts of alcohol, coffee, or strong tea. If it occurs frequently, you should take medication under the guidance of a doctor in a timely manner and do not use medication indiscriminately.

1. Beta-blockers

By blocking beta-receptors, it slows the heart rate. It is a commonly used drug to slow down the heart rate.

For patients with good heart function, prone to tension, and high blood pressure, short-acting propranolol (Inderal) can be used, 5 to 10 mg each time (10 mg per tablet) orally, 2 to 3 times a day.

Medium-acting metoprolol (Betaloc) is taken orally at 12.5 to 25 mg each time (50 mg per tablet), twice a day; or atenolol (Atenolol) is taken orally at 12.5 to 25 mg each time (50 mg per tablet), twice a day.

Or long-acting bisoprolol (Concor, Bossu), 5 mg orally each time (5 mg per tablet), once a day. If the heart rate is slower than 60 beats per minute, discontinue use.

2. Calcium antagonists

For example, non-dihydropyridine calcium channel blockers have an inhibitory effect on the sinoatrial node, slowing down the sinus heart rate. Commonly used ones include verapamil (Isapamil), which is suitable for patients with good heart function and high blood pressure. It can be taken orally at a dose of 40 mg each time (40 mg per tablet), 3 times a day, or with sustained-release tablets, half a tablet each time (240 mg per tablet), once a day. It may occasionally cause adverse reactions such as hypotension, lower limb edema, dizziness, and vertigo. If the heart rate is slower than 60 beats per minute, discontinue use.

There is also another non-dihydropyridine calcium channel blocker called diltiazem (Tianerxin), which does not slow down the heart rate as well as verapamil, but also has a blood pressure lowering effect and can relieve coronary artery spasm. It is suitable for patients with angina pectoris caused by coronary heart disease accompanied by hypertension and rapid heart rate. Take 1 tablet (30 mg) orally 3 times a day. Or sustained-release capsules, 1 capsule (90 mg) each time, 1 to 2 times a day. Adverse reactions such as dizziness, flushing, headache, constipation, hypotension and bradycardia are occasionally seen.

3. Digoxin

It is a cardiotonic drug. By stimulating the vagus nerve, the heart rate is reflexively slowed down. Suitable for patients with tachycardia and poor cardiac function. Take half a tablet to 1 tablet (0.25 mg each tablet) orally, 1 to 2 times a day. Be aware that this may cause gastrointestinal disturbances.

4. Reserpine

It is a peripheral adrenergic blocking drug. Suitable for patients with hypertension and rapid heartbeat. Take 1/2 to 1 tablet (0.25 mg per tablet) orally, 2 to 3 times a day. Excessive dosage can cause fatigue, weakness, headache, depression, anxiety, impotence, etc. Vomiting, stomach pain, bradycardia, bronchospasm, etc. are rare. It should be used with caution in patients with a history of depression, peptic ulcer, tremor paralysis, pheochromocytoma, etc.
