Myocarditis with complete atrioventricular block associated with herpes simplex virus infection: report of one case

Abstract

Myocarditis with complete atrioventricular block is a very unusual complication of the herpex simplex infection. We report a 10-year-old boy infected very likely by the herpes simplex virus and who presented with high fever, erythema multiforme, complete atrioventricular block, and Adams-Stokes seizures. Emergent temporary pacemaker was performed for bradycardia. A sixteen-fold rise in herpes simplex antibody titer by a complement fixation method occurred within two weeks. Normal cardiac rhythm recovered 11 days later with a sequela of complete right bundle branch block after 2 years follow-up.
