ABSTRACT
Introduction: Atrial fibrillation (AF) and pulmonary embolism (PE) share a complicated relationship. Pulmonary embolism has been associated with increased incidence and prevalence of AF. On the other hand, AF has also been associated with increased risk of PE in multiple cohort studies. What complicates the relationship further is that in some cases as in our case, patients presented with AF and were found to have PE.
Case Report: A 72-year-old female presented to the emergency department with respiratory distress and was found to have atrial fibrillation with rapid ventricular response. She worsened despite appropriate treatment for atrial fibrillation. She was found to have massive pulmonary embolism after she underwent echocardiogram and CT scan of chest. However, she deteriorated quickly and died within five hours of presentation to the emergency department.
Conclusion: Pulmonary embolism can precede, coexist or occur after atrial fibrillation. Clinicians should be alert about the complicated relationship of AF and PE.

Keywords: Atrial fibrillation, Anticoagulation, Cardioversion pulmonary embolism
