Regional Myocarditis due to Legionella Masquerading as Dual-Chamber Cardiac Arrhythmia

Abstract

Myocarditis, an inflammatory myocardial condition, often is associated with arrhythmias. Enhanced diagnostic capabilities have emerged from advanced imaging techniques such as fluorine-18–labeled deoxyglucose positron emission tomography and cardiac magnetic resonance imaging with late gadolinium enhancement. We present a rare case of Legionella myocarditis with concurrent dual-chamber arrhythmias while using multimodality imaging for diagnosis.
