Medications that lower heart rate

Medications that lower heart rate mainly include beta-blockers, calcium channel antagonists, and digitalis preparations. Among these, beta-blockers such as metoprolol and bisoprolol work by blocking beta receptors in the heart, inhibiting sympathetic nervous system activity, and thereby reducing the automaticity conduction of myocardial cells. They are among the most commonly used medications for lowering heart rate. Calcium channel antagonists like diltiazem and verapamil primarily reduce heart rate by slowing atrioventricular conduction and are suitable for various supraventricular arrhythmias. Digitalis preparations such as digoxin are primarily used for heart rate control in patients with heart failure. It should be noted that different medications have distinct indications and side effects. Patients should use these medications under a physician's guidance and undergo regular electrocardiogram and blood pressure evaluations to monitor heart rate changes. Additionally, patients should pay attention to medication dosage and timing, avoiding self-adjustment of doses or switching medications to prevent adverse reactions.
