心动过速性心肌病是由持续或频繁发作的心动过速引起心肌重构导致心脏扩大、心功能异常,心动过速及时根治后心功能和心脏结构可得到不同程度的逆转。临床上诊断该病主要是根据发生心动过速和心力衰竭的时间顺序,以及有效治疗心动过速后心功能的恢复情况来判定。对于心动过速性心肌病,治疗心动过速本身是关键,因此对于该病的诊断和治疗都要遵循“越早越好”的原则。 Tachycardia cardiomyopathy is caused by sustained or frequent attack of tachycardia myocardial remodeling led to heart enlargement, cardiac dysfunction, tachycardia and timely cure after heart function and cardiac structure can be different degrees of reversal. Clinic diagnosis of the disease is mainly based on the occurrence of tachycardia and heart failure in chronological order, and effective treatment of tachycardia after cardiac function recovery to determine. For tachycardia cardiomyopathy, the treatment of tachycardia itself is the key, so the diagnosis and treatment of the disease must follow the “sooner the better” principle.
