INTRODUCTION
Bundle branch reentry as a mechanism of ventricular tachycardia (VT) in endomyocardial fibrosis (EMF) is not described.
CASE REPORT
A 52-year-old woman with left ventricular (LV) EMF had VT needing cardioversion. She had mitral regurgitation and left bundle branch block, but no LV dilation or heart failure. During electrophysiological study, clinical VT could be easily induced, and it was confirmed to be bundle branch reentrant VT (BBRVT). She was treated with ablation of the right bundle branch.
CONCLUSION
BBRVT can occur in EMF even without cardiac dilatation. Its recognition is important, as radiofrequency ablation can be curative.
引言
束支折返作为心内膜心肌纤维化（EMF）中室性心动过速（VT）的一种机制尚未见报道。
病例报告
一名52岁患有左心室（LV）EMF的女性发生了需要心脏复律的室性心动过速。她有二尖瓣反流和左束支传导阻滞，但无左心室扩张或心力衰竭。在电生理研究期间，临床室性心动过速很容易被诱发，并被证实为束支折返性室性心动过速（BBRVT）。她接受了右束支消融治疗。
结论
即使没有心脏扩张，BBRVT也可发生于心内膜心肌纤维化。认识到这一点很重要，因为射频消融可能治愈该病。
