The drug of choice for sinus tachycardia

Sinus tachycardia is a relatively common symptom. When this symptom occurs again, the patient will face great pain. Fortunately, this symptom can be relieved and treated through certain methods. For example, many patients will choose some drugs to treat sinus tachycardia. So, what drugs can be used to treat sinus tachycardia? This will be introduced below!

1. Treatment principles

(1) Eliminate the cause and treat the primary disease.

(2) Treat the symptoms accordingly.

2. What medicines are generally used for sinus tachycardia?

Sinus tachycardia can be treated with drugs that slow down the ventricular rate. The more commonly used drug in clinical practice is metoprolol tartrate, which is a beta-blocker. The drug primarily inhibits ventricular conduction, thereby slowing the heart rate.

If sinus tachycardia is caused by myocardial ischemia, the patient should also be given drugs to nourish the myocardium, as well as drugs to promote blood circulation, remove blood stasis and improve circulation.

It is important to know the cause of the patient's illness. Only by finding out the cause can the symptoms be controlled. Sinus arrhythmia and tachycardia can be controlled by these drugs.

3. Principles of Medication

(1) Most cases caused by physiological or extracardiac factors do not require special treatment. The treatment of sinus tachycardia should focus on treating the primary disease, supplemented by symptomatic treatment when necessary. For sinus tachycardia caused by congestive heart failure, digitalis preparations, diuretics and vasodilators can be used. Correction of sinus tachycardia is often used as one of the indicators for controlling left heart failure.

(2) In the treatment of sinus tachycardia not caused by heart failure, such as sinus tachycardia caused by hyperthyroidism, the use of digitalis cannot slow the heart rate. Note: Digitalis overdose can also cause sinus tachycardia. For patients with sinus tachycardia caused mainly by sympathetic nerve excitement and increased catecholamines, beta-blockers, sedatives, etc. can be used.

(3) For the treatment of patients with acute myocardial infarction, when there is no obvious heart failure and the sinus rate remains >110 beats/minute, a small dose of beta-blockers such as oral atenolol or calcium channel blockers such as oral diltiazem can be temporarily tried to slow the heart rate. If necessary, the drug can be taken once every 8 to 12 hours. Sinus tachycardia secondary to left heart failure should be treated primarily for heart failure.
