After the ECG was obtained, the patient was admitted to the intensive care unit and actively rewarmed with infusions of warm normal saline and administration of a forced-air warming blanket. Serial cardiac biomarkers did not demonstrate evidence of myocardial necrosis (troponin I <0.04 ng/mL [to convert to micrograms per liter, multiply by 1]). After correction of the acidemia (pH 7.35) and rewarming (37.5°C), a repeated ECG 5 hours after the initial presentation demonstrated complete resolution of the previously identified J-point deviation (Figure 2). The patient regained consciousness and was extubated 2 days later.
