(FIT)-Module 2 Special Workshop: 12 Lead ECG for PVC and VT Localization-Stevenson Case 5 Answer

Video Transcription

Video Summary

The video discusses identifying and managing sustained ventricular tachycardia with a right bundle branch block configuration, indicating a left ventricular origin. Specifically, it focuses on idiopathic interfascicular reentrant ventricular tachycardia (VT), also known as Bellhausen VT, which involves the Purkinje system. This type of VT typically shows a superiorly directed frontal plane axis, and is often exercise-induced. A QRS duration of less than 140 milliseconds is typical, which differs from arrhythmias originating from the papillary muscles or the mitral annulus. Treatment often involves ablating the mid-left ventricular septal Purkinje site.
