Abstract:
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.
