Tachycardia potent drugs can be used in the category of beta blockers (bisoprolol), digitalis, amiodarone, and others. Tachycardia does not only refer to a separate disorder, but can be categorized into sinus tachycardia, atrial tachycardia, ventricular tachycardia and other types. The treatment for different types of tachycardia is different. 1. Sinus tachycardia: Certain diseases and triggers can cause sinus tachycardia in patients, so when treating it, the first thing to do is to target the cause and remove the triggering factors. For example, treatment of hyperthyroidism, heart failure and so on. If necessary, beta-blockers (labetalol), non-dihydropyridines (diltiazem) can be used in combination. 2. Atrial tachycardia (atrial tachycardia): Coronary heart disease, chronic lung disease, digitalis intoxication, etc. can be the cause of atrial tachycardia. Atrial tachycardia is mainly treated first for the cause of the disease, pulmonary disease to treat patients with hypoxemia, and digitalis intoxication to stop digitalis immediately. Next, the ventricular rate can be controlled with beta-blockers and non-dihydropyridine calcium channel blockers. Finally, to restore sinus rhythm, you can use amiodarone, ibutilide and so on. 3. Ventricular tachycardia: common in patients with organic heart disease such as coronary artery disease, cardiomyopathy. Need to terminate ventricular tachycardia such as lidocaine, amiodarone. It is also necessary to prevent recurrence. Actively search for reversible lesions that induce ventricular tachycardia and treat ventricular tachycardia, such as ischemia and hypotension.
