Sustained Bundle Branch Reentrant VT. Radiofrequency catheter ablation of the left bundle branch (LBB) was attempted in a patient with sustained bundle branch reentry. During sinus rhythm, the QRS had a complete LBB block pattern, and the LBB was activated retrogradely (transseptal). Ablation of the LBB eliminated inducibility of the tachycardia, while the QRS complex and the duration of the HV interval (70 msec) remained unchanged. Successful ablation of the LBB eliminated bundle branch reentry and yet maintained the anterograde conduction properties of the His-Purkinje system, obviating implantation of a permanent pacemaker.
持续性束支折返性室性心动过速。在一名患有持续性束支折返的患者中尝试进行左束支（LBB）的射频导管消融。在窦性心律时，QRS波呈完全性左束支传导阻滞图形，且左束支呈逆向（经间隔）激动。消融左束支消除了心动过速的诱发，而QRS波群和HV间期（70毫秒）的时长保持不变。成功消融左束支消除了束支折返，同时保留了希氏 - 浦肯野系统的前向传导特性，从而无需植入永久性起搏器。
