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

Video Transcription

Video Summary

The video discusses telemetry tracing related to Sotilol, a class III antiarrhythmic drug with reverse-use dependence, meaning its effects are stronger at slower heart rates. Sotilol blocks IKR, prolonging the QT interval, which increases risks, especially in females. It also has beta-blocking properties, potentially causing sinus bradycardia with pauses. The video identifies a classic short-long-short pattern triggering ventricular fibrillation without AV-block. It concludes by explaining why certain answers are incorrect and wishes viewers good luck if they are preparing for medical board exams.
