心动过速性心肌病指继发于长期心动过速导致的左室并和(或)心房功能异常,一旦心动过速终止,心功能异常可以完全或部分恢复。心动过速性心肌病在持续心动过速的动物模型和患者都明确证实,心动过速性心肌病的诊断为回顾性,即心律失常恢复正常后,损害的心功能得到恢复;临床医师应该认识到不能解释的心功能异常有可能就是心动过速性心肌病,而控制心律失常可能就会改善心功能。
Tachycardia cardiomyopathy refers to secondary to left ventricular dysfunction and (or) atrial dysfunction secondary to long-term tachycardia. Once the tachycardia terminates, cardiac dysfunction can be completely or partially recovered. Tachycardia cardiomyopathy in continuous tachycardia in animal models and patients have clearly confirmed that the diagnosis of tachycardia cardiomyopathy was retrospective, that is, after the return of normal arrhythmia, impaired cardiac function has been restored; clinicians should recognize To can not explain the abnormal heart function may be tachycardia cardiomyopathy, and control of arrhythmia may improve cardiac function.
