title: Propranolol toxicity presenting with early repolarization, ST segment elevation, and peaked T waves on the ECG.
abstract: A 58-year-old man presented stating that he had voluntarily ingested eight 80-mg propranolol tablets in approximately 24 hours. He was asymptomatic at the time of presentation. Subsequently, the patient developed only mild bradycardia. The ECG showed sinus bradycardia with striking early repolarization, ST segment elevation, and peaked T waves. These ECG abnormalities represent an unusual pattern for beta-adrenergic blocking agent toxicity.
