Tachycardia mediated cardiomyopathy (TMC) is a reversible form of dilated cardiomyopathy that can occur with most supraventricular and ventricular arrhythmias. Despite the plethora of literature describing this entity in animal models, as well as humans, it remains poorly understood. Over the last decade, new etiologies of TMC, such as frequent premature ventricular complexes in normal hearts, have been identified. Recent advances in catheter-based ablation therapies, particularly for atrial fibrillation and ventricular arrhythmias, have added a new dimension to the treatment of this condition. This review describes the pathophysiology, proposed mechanisms, clinical features and management in various arrhythmic conditions.
心动过速性心肌病（TMC）是一种可逆转的扩张型心肌病，可发生于大多数室上性和室性心律失常。尽管有大量文献描述了这种疾病在动物模型和人类中的表现，但人们对其仍知之甚少。在过去十年中，TMC 的新病因已经被确定，例如在正常心脏中频繁出现的室性早搏。导管消融治疗技术的最新进展，特别是在治疗房颤和室性心律失常方面，为这种疾病的治疗增添了新的维度。本综述描述了各种心律失常情况下的病理生理学、提出的机制、临床特征和治疗方法。
