High heart rate, there is no absolute fastest treatment, can use drug treatment and surgical treatment and other methods. 1. Sinus tachycardia: The treatment of sinus tachycardia should be directed at the cause of the disease and the removal of the predisposing factors, such as the active treatment of heart failure, correction of anemia, and control of hyperthyroidism. If necessary, beta-blockers (metoprolol), non-dihydropyridine calcium channel antagonists (diltiazem) can be used alone or in combination, and if ineffective, drugs such as ivabradine can be used for treatment. If the drugs are ineffective and symptoms are significant, catheter ablation may be considered. 2. Supraventricular tachycardia: In the acute stage, stimulation of the vagus nerve and direct current resuscitation can be used for treatment. Verapamil, propafenone and other drugs can be used for treatment. If ineffective, adenosine, digitalis, amiodarone and other drugs can be used for treatment. 3. Ventricular tachycardia: Myocardial ischemia can lead to ventricular tachycardia, first of all, we should recanalize the blood vessels to improve myocardial blood supply, and at the same time, we should use beta-blockers, such as labetalol and bisoprolol. Catheter ablation and implantation of cardioverter-defibrillator can also be used for treatment. The above medications are recommended to be used under the guidance of a doctor. There are many causes of fast heart rate, so it is recommended to go to the hospital in time to find out the cause and treat it promptly.
