Anaplasmosis-Induced Atrial Flutter Resolving With Antibiotic Therapy
We describe a case of a 56-year-old man with recent tick exposure who presented in atrial flutter with variable atrioventricular block after 3 days of fever, chills, and arthralgias. The patient was successfully treated and stably returned to sinus rhythm after initiation of antibiotics without cardioversion and was found to be positive for A. phagocytophilum but negative for Lyme disease. To our knowledge, this represents the first reported case of anaplasmosis-associated atrial flutter. As infections increase in incidence, clinicians in endemic areas should be aware of the potential manifestations and treatment considerations of tick-borne carditis.
