A male patient in their early 50s with no history of prior known diseases was admitted to the hepatobiliary surgery unit with epigastric pain and jaundice of 2 weeks. Electrocardiogram (ECG) findings at admission were normal. On the third day of admission, the patient experienced a sudden squeezing pain in the anterior chest at rest, with a heart rate of 44 beats/min, blood pressure of 97/60 mm Hg, and oxygen saturation of 98%. The ECG (, A) showed troponin I level of 0.107 ng/mL (normal reference value, 0?to approximately-0.034 ng/mL; to convert to micrograms per liter, multiply by 1). Isoproterenol was immediately administered by intravenous infusion due to a significantly decreased heart rate. About 20 minutes later, the patient reported that the pain was relieved, and a repeat ECG was done (, B).
