Abstract: Arrhythmia-induced cardiomyopathy（AIC）is a kind of cardiomyopathy caused by sustained or recurrent arrhythmias，the main clinical manifestations of which are cardiac dilatation and cardiac dysfunction， and blockade arrhythmia could result in partial or complete resolution of the left ventricular ejection fraction. Arrhythmia is hard detected in children，therefore the epidemiology of AIC may be underestimated. Arrhythmias blockade could result in partial or complete resolution of the left ventricular ejection fraction. Both drug therapy and catheter ablation are standard treatment that have been used to treat AIC. Early diagnosis and reasonable treatment are significant to improve the prognosis. This paper summarized domestic and foreign literature on the various types of AIC，systematically reviewed the epidemiology，definition，pathogenesis，clinical symptoms，diagnosis，and the latest treatment methods，and discussed the current treatment at home and abroad.

Key words: arrhythmia, children, cardiomyopathy
