The case for quinidine: Management of electrical storm in refractory ventricular fibrillation

摘要

Electrocardiogram (ECG) recordings. Telemetry strip demonstrating sinus rhythm with short-coupled premature ventricular contraction (PVC)–initiated polymorphic ventricular tachycardia. ECG immediately after initial cardioversion with short-coupled (240 ms) PVCs. Note the right bundle branch block, left anterior hemiblock morphology of the PVC, typical for Purkinje ectopy in the distal left posterior fascicle region.
