CME Credits: 1.00

Released: 2023-10-30

A patient in their 40s with a history of end-stage kidney disease secondary to hypertension and diabetes status and deceased-donor kidney transplant 2 months prior presented to the emergency department (ED) with fatigue, nonproductive cough, weakness, and dyspnea on exertion. On arrival, vital signs recorded a temperature of 100.3 °F, heart rate of 102 bpm, blood pressure of 134/69 mm Hg, respiratory rate of 20, and oxygen saturation of 94% on room air. Physical examination was unremarkable and initial laboratory results were near baseline. A chest radiograph (CXR) demonstrated bibasilar patchy opacities consistent with atelectasis. Given the patient’s immunosuppressed status, the patient was admitted to the hospital for further infectious work up. A baseline electrocardiogram (ECG) from an ED visit for anemia and similar symptoms 2 days prior is shown (, A). Overnight on hospital day 1, the patient developed new chest pain and hypoxia requiring supplemental oxygen, and the next morning, they became acutely hypotensive necessitating transfer to the intensive care unit (ICU). An ECG from the initial episode of chest pain (, B) and a subsequent ECG before ICU transfer (, C) are shown.
