摘要
The core treatment of rapid arrhythmiainduced heart failure(HF)is to control the ventricular rate to an optimized lower level,which is usually achieved with various anti-arrhythmic drugs.However,arrhythmias may not respond well to pharmaceutical treatment for various reasons.Iatrogenic atrioventricular(AV)node ablation needs to be performed under these extreme conditions to lower the patient’s heart rate.
