(FIT)-Module 5 Workshop 9: Arrhythmia Case Studies (Putting It All Together for the Boards)-Miller Case 5B Question

Video Transcription

Video Summary

During a case study of an arrhythmia, overdrive pacing was conducted from the right ventricle, testing various cycle lengths. The return intervals from the last paced complex to the first ventricular tachycardia (VT) complex were analyzed. Based on the findings, the discussion revolves around identifying the most likely arrhythmia mechanism, considering options like focal automaticity, micro reentry within the left anterior fascicle, and triggered activity due to either delayed or early afterdepolarizations.
