Normal human heart rate range is 60-100 beats per minute, heart rate more than 110 beats per minute can be diagnosed as tachycardia, occasional physiological tachycardia without medication, exercise or emotional excitement when the heart rate increases is normal. Tachycardia caused by heart disease and other pathologic factors can be treated with beta-blockers such as propranolol, calcium channel blockers such as verapamil, digoxin and other digitalis drugs.
1. β-blockers: such as propranolol, metoprolol, etc. β-blockers can prolong ventricular diastole, inhibit myocardial contractility, reduce cardiac work, reduce myocardial oxygen consumption, and reduce heart rate.
2. Calcium channel blockers: such as verapamil and diltiazem. Calcium channel blockers can diastole coronary artery, can reduce the heart rate, for the treatment of supraventricular tachycardia and arrhythmia has an important role.
3. Digitalis drugs: such as digoxin. Digitalis drugs can increase myocardial contractility, often applied to patients with rapid heart rate combined with heart failure.
It is recommended that patients seek medical attention as soon as possible to clarify the cause of the disease, and strictly follow the medical prescription of drugs to prevent serious adverse reactions.
