The choice of medication for rapid heart rate is based on the cause and type of rapid heart rate. If it is physiological rapid heart rate caused by exertion, emotional excitement, exercise, tension, anxiety, etc., it is usually not necessary to take medication and can be relieved by itself after rest. If the rapid heart rate is caused by disease, you should choose the appropriate medication for treatment. Clinically, rapid heart rate is tachycardia, common types and treatment drugs include the following: 1, sinus tachycardia: severe anemia, hyperthyroidism, hypokalemia, etc. can lead to sinus tachycardia, the patient may have panic, chest tightness symptoms. Beta-blocker type drugs can be considered to control the heart rate, such as metoprolol tartrate, bisoprolol, etc. The cause of sinus tachycardia should also be sought to treat the primary disease. If the patient has severe anemia, oral drugs should be taken to correct the anemia, and blood transfusion if necessary; if the patient has hyperthyroidism, drugs such as propylthiouracil and methimazole can be taken orally; for electrolyte disorders such as hypokalemia induced tachycardia, potassium tablets can be taken orally to correct electrolyte disorders; 2. Non-sinus node tachycardia: common ones include supraventricular tachycardia or atrial fibrillation, atrial flutter If necessary, intravenous drugs can be applied, and radiofrequency ablation can also be considered, while actively correcting the cause; 3, ventricular tachycardia: this condition is relatively dangerous, persistent ventricular tachycardia, which may endanger the patient’s life, or even ventricular fibrillation, which may lead to sudden death. Both cases may not work well with oral medication and require emergency electrical cardioversion or direct treatment for the cause, once it occurs, prompt medical treatment should be sought.
