Abstract
© 2019 Elsevier Inc. Introduction: Acute electrocardiogram abnormalities are common in patients afflicted with pulmonary embolism (PE). Rarely, a patient with acute pulmonary embolism and electrocardiogram changes may have an underlying conduction abnormality that complicates their course. Case presentation: We describe a patient with known history of left bundle branch block who presented with acute PE and developed a right bundle branch block, which devolved into complete third degree heart block without ventricular escape rhythm and led to concomitant hemodynamic compromise. Discussion: Given the rarity of this clinical scenario, we call for clinicians to be aware of PE-associated conduction pathology as well as the possibility that malignant cardiac conduction blocks may occur in the setting of PE particularly if the patient is known to have underlying conduction system disease. We emphasize the importance of continuous telemetry monitoring in patients presenting with PE as these types of arrhythmic complications and hemodynamic decompensation has been observed.
