Man Collapses While Playing Basketball

ANSWER
The correct interpretation is normal sinus rhythm with an acute anterior MI (STEMI) and inferolateral injury. In the absence of left ventricular hypertrophy and left bundle-branch block, an acute anterior MI manifests with new ST elevations ≥ 0.1 mV, measured at the J point in leads V₂-V₃. Inferolateral injury is indicated by ST elevations in leads II, III, and aVF, as well as ST elevations in leads V₄-V₆.

Laboratory findings confirmed the diagnosis of a new infarction, and cardiac catheterization revealed significant blockage in the proximal left anterior descending and circumflex coronary arteries. These were treated percutaneously, and the patient recovered without sequelae.
