2025 Multiprofessional Critical Care Review: Adult Online-Analysis and Therapy of Ventricular Arrythmias

Analysis and Therapy of Ventricular Arrythmias

Video Transcription

Video Summary

The speaker explains how to differentiate ventricular tachycardia (VT) from supraventricular tachycardia (SVT) with wide QRS complexes using the Scan and Zoom algorithm, focusing on criteria like AV dissociation, capture/fusion beats, extreme axis deviation, precordial concordance, RS interval >100ms, and atypical bundle branch block patterns. VT is more likely if over 35 or with heart disease. Management includes immediate treatment of unstable patients and pharmacologic options: amiodarone or lidocaine for unstable VT, procainamide for stable VT, and beta-blockers for prevention. Magnesium is reserved for torsades de pointes.
