Cardiac Manifestations of Lyme Disease
Lyme carditis is an uncommon manifestation of Lyme disease. Most cases present with heart block of varying degrees, but the spectrum of disease includes other transient arrhythmias and structural manifestations, such as myopericarditis or cardiomyopathy. Antibiotics hasten the resolution of Lyme carditis, and cardiac pacing can be an adjunctive therapy. Outcomes are generally good, but there are rare fatalities associated with Lyme carditis. The latter underscores the continued need for improved modes of prevention of Lyme disease and the importance of its early recognition and treatment.
