Unique Ventricular Tachycardia Originating from the Right Bundle Branch.

Ventricular tachycardia (VT), a common arrhythmia, frequently originates from in the right ventricular outflow tract, left ventricular outflow tract, aortic sinus, and left ventricular papillary muscle but infrequently from the His-Purkinje system, whereas the VT stemming from the right bundle branch has rarely been reported. Here we reported a case with of VT originating from the right bundle branch which was subsequently successfully treated with radiofrequency ablation and demonstrated the electrocardiac features of VT using an electrophysiological examination.
