(FIT)-Module 4 Workshop 7: Electrocradiogrpahic and Electrophysiological Correlations, Atrial Fibrillation, Clinical Scenarios and Syndromes-Asirvatham Case 1 Answer

Video Transcription

Video Summary

The video transcript discusses the diagnosis of arrhythmias based on simultaneous or near-simultaneous atrial (A) and ventricular (V) signals. It highlights conditions like AV node re-entry, junctional tachycardia, and atrial tachycardia, focusing on the possible involvement of the left atrium in the circuit. The discussion notes that certain anatomical blocks, like the Eustachian ridge, might necessitate the use of left atrial myocardium. This could lead to an unusual electrical activation sequence, with distal coronary sinus (CS) activation occurring earlier than proximal, distinguishing it from right free wall-originated tachycardias.
