What medicine should tachycardia take

summary

Tachycardia is mainly divided into physiological and pathological two cases, physiological appropriate rest can be restored, and if it is pathological need drug treatment. Let's take a look at what medicine tachycardia should take.

What medicine should tachycardia take

Drug 1: beta blocker: this kind of drug will block beta receptor, weaken myocardial contractility and slow down heart rate. Propranolol (propranolol), 5-10 mg per time (10 mg per tablet), 2-3 times a day, metoprolol (Betaloc), 12.5-25 mg per time (50 mg per tablet), twice a day, or atenolol (atenolol), 12.5-25 mg per time (50 mg per tablet), twice a day for patients with good cardiac function, easy tension and high blood pressure. The drug has side effects, such as bradycardia, hypotension and atrioventricular block. If the heart rate is lower than 60 beats / min, it will be stopped.

Drug 2: verapamil (verapamil): a calcium antagonist. It can selectively inhibit the flow of calcium ions to the node area of sinoatrial node and atrioventricular node, so as to reduce self-regulation and slow down heart rate. It is suitable for patients with tachycardia with good cardiac function and high blood pressure. Oral administration, 40-80 mg each time (40 mg each tablet), 3 times a day, or sustained release tablets, 1 tablet each time (240 mg), 1 time a day. Occasionally, it can cause hypotension, peripheral edema, dizziness, vertigo and other adverse reactions. If the heart rate is lower than 60 beats / min, it will be stopped.

Drug 3: diltiazem (tianerxin): a calcium antagonist. Take one tablet (30 mg) orally three times a day. The maximum dose was 90 mg, three times a day. If you take sustained-release capsules, 1 capsule (90 mg) each time, 1-2 times a day. Occasionally, dizziness, flushing, headache, constipation, hypotension and other adverse reactions were observed.

matters needing attention

Tachycardia is mostly caused by physiological reasons, such as emotional excitement, physical activity, eating, drinking, tea or coffee, etc.; it can also be seen in pathological reasons, such as fever, cardiac neurosis, myocarditis, etc.; the frequent occurrence of tachycardia requires etiology and symptomatic treatment.
