👤 Michael, 52, pacing in triage

Wife says he's "more anxious than usual." He keeps rubbing his left arm. Chest feels "heavy."

Looks like anxiety. But ECG at 8 minutes → ST depression V3-V5. Troponin elevated.

Diagnosis: NSTEMI.

His "anxiety" was his body responding to ischemia. The ECG you almost skipped saved his life.
