摘　　要：心律失常性心肌病是由心律失常引起或介导的可逆性扩张型心肌病,可见于各年龄段儿童,目前的发病率是被低估的。导致本病的具体病理生理机制尚不清楚。临床诊疗上,判断心律失常是心功能障碍的病因还是结果经常很困难,本病经常在心律失常得以控制,心功能改善后才能确诊。快速性心律失常、室性期前收缩、左束支传导阻滞、心室预激均可导致心律失常性心肌病的发生。早期识别和控制心律失常可逆转心功能,心律失常复发可致心功能迅速下降。Arrhythmia-induced cardiomyopathy(AIC)is an reversible dilated cardiomyopathy and appears to occur at any age.The morbidity of AIC is unclear and likely underestimated.The pathophysiology and mechanism of AIC is unknown.It is often difficult to determine whether arrhythmias are the cause or result of cardiac dysfunction.The diagnosis of AIC can be only confirmed after recovery or improvement of cardiac function after elimination of the tachyarrhythmia.Tachycardias,ventricular premature contraction,left bundle branch block and ventricular preexcitation are known to trigger AIC.Appropriate diagnosis and treatment of AIC can reverse cardiac function.However,arrhythmia recurrence can lead to rapid recurrence of AIC and symptoms of heart failure.
