| Popis: | A 74-year-old female with a history of diabetes presented with chest pain and shortness of breath for two days. She was hypoxic to an oxygen saturation of 60% in the emergency department, requiring bilevel positive airway pressure (BiPAP) to maintain saturations. Chest X-ray demonstrated bilateral hazy opacities suspicious for viral pneumonia. Coronavirus disease 2019 (COVID-19) was confirmed. Right bundle branch block (RBBB) with left anterior fascicular block was noted on admission electrocardiogram (ECG). Cardiac enzymes and brain natriuretic peptide levels were within normal limits. After noting frequent pauses on telemetry, a repeat ECG was performed that demonstrated RBBB with left posterior fascicular block as well as second-degree atrioventricular block (Mobitz type II). Transcutaneous pacing pads were placed, and atropine was placed at the bedside. Cardiac enzymes remained negative. Interleukin-6 levels were elevated at 159 pg/mL. Hydroxychloroquine was deferred due to the patient's arrhythmia and prolonged QTc. Tocilizumab was deferred due to the patient's age. The patient's oxygen requirements and mental status continued to worsen. She continued to desaturate despite maximal BiPAP therapy and eventually died. Cardiac involvement in COVID-19, whether caused primarily by the virus, secondary to its clinical sequelae, or even due to its treatment, cannot be ignored. Further high-quality research is needed to clarify the cardiac pathophysiology. Thorough cardiac exams with electrocardiographic correlation should be performed on all patients with COVID-19. Clinicians should not hesitate to consult cardiovascular services in the event of abnormality. |
