(FIT)-Module 5 Workshop 8: Device Cases-Poole Case 3 Answer

Video Transcription

Video Summary

The most likely diagnosis for the analyzed case is AV node reentry tachycardia (AVNRT). This conclusion is reached by assessing one-to-one tachycardia characteristics, including the onset and termination, which begins with atrial beats and ends in an atrial signal. The electrogram morphology matches with supraventricular tachycardia, and the device confirms a consistent V-to-A interval with a variable A-to-B interval, eliminating atrial tachycardia. The analysis finds that the cycling of intervals indicates AVNRT, ruling out ventricular tachycardia and atrial tachycardia, making AVNRT the most plausible diagnosis.
