Abstract：In the past, arrhythmia-induced cardiomyopathy has long been defined as a kind of clinical syndrome. Its pathogenic mechanism is long-standing tachycardia impairs left ventricular function which results in enlarged ventricle, declined cardiac function, and finally heart failure. After] heart rate or tachyarrhythmia is controlled, cardiac function can be recovered partially or fully, and the clinical syndrome can also be called tachycardia-induced cardiomyopathy. With the progress of cardiac electrophysiology, more and more types of arrhythmias can be cured once and for all. Various types of arrhythmias are found which can induce cardiomyopathy. Therefore, the concept of tachycardia-induced cardiomyopathy has developed and been transformed into the concept of arrhythmia-induced cardiomyopathy. Different types of arrhythmia-induced cardiomyopathy differ in triggering mechanisms and mainstream therapies.
