(FIT)-Module 3 Workshop 5: Invasive and Non-Invasive Correlation-Marchlinski Case 3 Answer

Video Transcription

Video Summary

In reviewing the answer about ventricular premature depolarizations (VPD), the transcript highlights patterns indicating a right coronary cusp origin. Key features include positive in Lead I, Lead II greater than III, and early precordial transition typical of a left bundle branch block in V1. In contrast, VPDs from other locations, like the LV summit, typically show a negative QRS in Lead I and a different precordial transition pattern. VPDs with epicardial origins can be mapped and ablated via percutaneous approaches, displaying right bundle-ish morphology and specific transition patterns unlike the right coronary cusp origin.
