  Figure 1. Initial 12-lead electrocardiogram showing sinus rhythm with an extended ST-segment elevation in the precordial leads corresponding to the anteroseptoapical region

• 

  Figure 2. Day 5 12-lead electrocardiogram showing polymorphic ventricular tachycardia initiated by a short-coupled premature ventricular contraction manifesting negative precordial concordance in leads V1–V6, and right axis and D2-D3 discordance pointing toward the apical origin. QTc within normal limits.
