Figure 1 Twelve-lead electrocardiogram in the intensive care unit after resuscitation and a single empiric dose of intravenous amiodarone administered in the emergency department. Corrected QT interval (QTc) measures 790 ms. HeartRhythm Case Reports 2018 4, 576-579DOI: (10.1016/j.hrcr.2018.08.013) Copyright © 2018 Heart Rhythm Society Terms and Conditions

Figure 2 Top panel shows electrocardiographic tracings from the telemetry monitor showing prolonged QT (LQT) and initiation of torsades de pointes (TdP) polymorphic ventricular tachycardia. Bottom panel corresponds to the electrocardiographic registration of 1 of multiple external defibrillations (white arrow) prior to initiation of intravenous isoproterenol. Gray arrows show premature ventricular contractions at the end of the QT interval that correspond to early afterdepolarizations.
