Drugs for controlling ventricular rate: patients can use β-blockers, such as atenolol, metoprolol, etc., and calcium channel blockers, such as diltiazem, verapamil, etc., and digoxin can be used for treatment, which can effectively slow down ventricular rate and reduce the patient’s atrial tachycardia. 2. Reversal of sinus heart rate drugs: commonly used drugs for antiarrhythmic drugs, such as quinidine, procainamide, amiodarone, propafenone, etc., can make the sinus rhythm back to normal. Specific medication also need to go to the hospital to confirm the diagnosis, under the guidance of the doctor for use, the patient must not be unauthorized use of medication, stop or change the drug, drug treatment effect is not obvious patients, but also comply with the doctor’s instructions for surgical treatment, such as radiofrequency ablation.
