A 15-year-old boy presented to the local hospital with 19 h of chest tightness. The
electrocardiogram (ECG) showed sinus rhythm with mild ST-segment elevation in precordial
leads V2–V6 (Figure 1), troponin I was 1.87 ng/mL (0–0.30 ng/mL), and creatine kinase-MB fraction was 51
U/L (0–25 U/L). Transthoracic echocardiography demonstrated a normal left ventricular
ejection fraction (69%) and no regional wall motion abnormalities.
Figure 1Electrocardiogram showed sinus tachycardia (101 beats/min) and mild elevation of ST-segment
in precordial leads V2–V6 (white arrow).
