(FIT)-Module 4 Workshop 6: Electrocardiographic and Electrophysiological Correlations-Asirvatham Case 2 Answer

Video Transcription

Video Summary

The transcript discusses various types of tachycardia, emphasizing AV nodal reentry, junctional tachycardia, and Hiss-Munru tachycardia. It notes distinguishing features such as the presence of more ventricular than atrial electrograms and potential blocks to the atrium. Differentiating factors like VA intervals and signal locations are mentioned. It highlights that in AV nodal reentry, despite typically having concurrent atrial and ventricular activity, variability, like isolated atrial spikes, can occur. The discussion suggests excluding free wall accessory pathways due to their distinct characteristics and focuses on the nature of AV nodal reentry.
