Atrial fibrillation is a disease with abnormal heart rhythm. Atrial fibrillation has various causes and is a common arrhythmia, and whether it can be cured is related to the type of atrial fibrillation. 1, the first occurrence of atrial fibrillation patients, atrial fibrillation most of the 1-2 days of self-reversal to sinus rhythm, so for patients without organic heart disease and mild clinical symptoms, give symptomatic treatment, severe symptoms can be considered drug resuscitation. 2, permanent atrial fibrillation persistent atrial fibrillation for more than a year is permanent atrial fibrillation, this type of atrial fibrillation treatment prognosis is relatively poor, it is difficult to restore the normal heart rhythm. Drug therapy can not maintain sinus rhythm, need to control the ventricular rate and the necessary anticoagulation therapy, can be controlled by radiofrequency ablation surgery, but the success rate is not high. 3, persistent atrial fibrillation The duration of atrial fibrillation is greater than 48 hours is persistent atrial fibrillation, this situation can choose drug control, under the guidance of the doctor choose anti-arrhythmic drugs, if necessary anticoagulation. Generally can not be self-recovery, the success rate of drug re-correction is low, often need electric re-correction. 4, paroxysmal atrial fibrillation Atrial fibrillation duration is generally less than 48 hours, mostly self-limiting, but prone to recurrent episodes, the use of drug resuscitation is recommended. In addition, drugs should be used to control the ventricular rate, and if necessary, anticoagulation therapy.
