Polymyositis-Induced Atrial Flutter: A Rare and Unexpected Arrhythmia in an Idiopathic Inflammatory Myopathy.

Abstract

We describe a 28-year-old Caribbean-Black female with polymyositis-associated atrial flutter during an acute flare episode for which she was successfully managed with guideline-directed medical therapy and noninvasive positive pressure ventilation. The clinician should be cognizant of this rare association, especially in young patients who present with symptomatic arrhythmias and chronic, preexisting idiopathic inflammatory myopathies.
