Atrial flutter should be timely to the regular hospital cardiology department, can be treated with drug therapy, electrical cardioversion therapy and surgical treatment. 1. Drug therapy: anti-arrhythmic drugs such as amiodarone and ibutilide can make patients change the rhythm to normal sinus rhythm and reduce the risk of recurrence. Digitalis drugs such as digoxin, beta-blockers such as metoprolol, and calcium channel blockers such as diltiazem do not have the effect of transrhythmia, but they can reduce the ventricular rate and improve symptoms. All of the above drugs are recommended to be used under doctor’s supervision. 2. Electric cardioversion: DC cardioversion can terminate atrial flutter, but it needs to be combined with medication or surgery to prevent recurrence. 3. Surgery: Radiofrequency ablation can inhibit the abnormal conduction pathway of electrical impulses in the atria and cure atrial flutter, which is recommended as the first choice for those who have no effect of drug treatment. Atrial flutter patients are recommended to go to the Department of Cardiology of regular hospitals for timely consultation and treatment.
