Answer 1 Acute pericarditis. The ECG shows diffuse concave ST-segment elevations with PR-depression, which are classic changes seen in acute pericarditis. Acute MI is incorrect because in infarction the ST-segment elevations are typically localized and convex with rare PR-segment depression. Pulmonary embolus is incorrect because in this condition the ST-segment elevations are also localized, usually to leads III, aVF, and V1. With early repolarization, the ST segments are usually elevated in the mid precordial leads; V4 is the most prominent, and it has a notch at the J point (where the QRS complex and ST segment meet).
