Figure 4 Electrocardiogram rhythm strip demonstrating polymorphic ventricular tachycardia. The single-lead rhythm strip documents the onset of polymorphic ventricular tachycardia with a ventricular rate of approximately 150 bpm, characterized by substantially widened (> 240 ms) and deformed QRS complexes approaching a sine-wave pattern, accompanied by severe repolarization abnormalities secondary to global myocardial electrical instability. This rhythm carries a high risk of degeneration into ventricular fibrillation, which subsequently developed.
