摘要

双室开窗测图（OWM）结合高密度测图显示外侧三尖瓣环早期房室传导，与Mahaim纤维一致。针对心室插入部位的导管消融可成功消除副通路和消除心动过速。

Dual Chamber Open Window Mapping and High-Density Mapping for Atrioventricular Reentrant Tachycardia Associated With Atrioventricular Mahaim Fiber

Dual-chamber open-window mapping (OWM) combined with high-density mapping revealed early atrioventricular conduction on the lateral tricuspid annulus, consistent with a Mahaim fiber. Catheter ablation targeting the ventricular insertion site led to successful elimination of the accessory pathway and noninducibility of tachycardia.
