Darting Waves and Diagnostic Twists

A 40-year-old man presented with chest pain and questionable lateral lead ST-segment elevations on electrocardiogram and T waves with bifid morphology. Blood pressure and heart rate were 129/66 mm Hg and 98 beats/min, respectively. Laboratory results revealed cardiac troponin of 5 ng/mL, magnesium of 1.6 mg/dL, potassium of 4.3 mmol/L, unremarkable renal function, thyroid stimulating hormone <0.010 ulU/mL, free thyroxine of 2.90 ng/dL, and free triiodothyronine of 376.1 ng/dL.

Abstract

A 40-year-old man presented with chest pain and questionable lateral lead ST-segment elevations on electrocardiogram and T waves with bifid morphology. Blood pressure and heart rate were 129/66 mm Hg and 98 beats/min, respectively. Laboratory results revealed cardiac troponin of 5 ng/mL, magnesium of 1.6 mg/dL, potassium of 4.3 mmol/L, unremarkable renal function, thyroid stimulating hormone <0.010 ulU/mL, free thyroxine of 2.90 ng/dL, and free triiodothyronine of 376.1 ng/dL.
