(FIT)-Module 4 Workshop 6: Electrocardiographic and Electrophysiological Correlations-Asirvatham Case 1 Answer

Video Transcription

Video Summary

The discussion analyzes an arrhythmia's features to determine its origin. A negative lead one suggests a left body origin, ruling out the posterior LV apex. The arrhythmia likely originates from the mitral annulus or anterior intraventricular vein region. Right side body possibilities like the RVOT free wall are dismissed due to positive lead one expectation. The assessment emphasizes the arrhythmia's leftward or posterior orientation, reflected in lead one and B1, guiding the approach for mapping and potential ablation.
