title: Suspected Bartonella-associated myocarditis and supraventricular tachycardia in a cat.
abstract: A 4-year old female spayed domestic short hair cat presented for evaluation of a tachyarrhythmia identified on routine physical examination. Supraventricular tachycardia (SVT) was identified on electrocardiogram (ECG). Echocardiogram failed to identify any structural heart disease. A positive Bartonella antibody titer was identified on serological evaluation. The cat received anti-arrhythmics for control of the SVT and azithromycin for Bartonella. After completion of antibiotic therapy, a four-fold decrease in the Bartonella antibody titer was measured and the cat was eventually weaned off anti-arrhythmic medications. At 1 week, 1 month and 3 month re-checks off all therapy, no SVT was identified.
