ABSTRACT
Murine typhus is a flea-borne infectious disease caused by Rickettsia typhi, of which myocarditis is a rare complication in the acute disseminating phase. A 62-year-old female presented with a fever and was diagnosed with murine typhus. She was treated with doxycycline and discharged after complete resolution of the fever. However, recurrent presyncope and exertional dyspnea developed 6-8 weeks later. Complete atrioventricular (AV) block with a wide QRS escape rhythm and a left bundle branch block configuration was documented. Subacute myocarditis was diagnosed based on persistent cardiac troponin-I elevation and typical cardiac magnetic resonance imaging findings. A permanent pacemaker was implanted for symptomatic complete AV block. Few reports of myocarditis in murine typhus have been published. We report a case of murine typhus myocarditis complicated by complete AV block in the late convalescence phase.
