A patient in their 50s was admitted to the intensive care unit with severe COVID-19 pneumonia. Their medical history was notable for hypertension and diabetes for 10 years. At presentation, the patient’s oxygen saturation was 87% on room air and improved to 94% with oxygen supplementation. They were treated with steroids and parenteral anticoagulation. However, there was progressive deterioration that required mechanical ventilation and inotropic support by the seventh day of hospitalization. A 12-lead electrocardiogram (ECG) was performed because a ST-segment abnormality was observed on telemetry (Figure).
Questions: What is the abnormality in the ECG? What is the immediate concern regarding management?
