Complete atrioventricular block persisting after regression of infectious myocarditis.
Atrioventricular block is usually transient during the course of infectious myocarditis. We report the case of a patient presenting with complete infra-hisian atrioventricular block occurring in the setting of infectious myocarditis and in whom a pacemaker should be finally implanted. Borderline serologies for picornavirus were present 6 weeks later. Complete atrioventricular block persisted during the two years of follow-up despite otherwise complete regression of the myocarditis. We then discuss the main features of conduction disturbances complicating infectious myocarditis, including a list as complete as possible of all the causal agents possibly involved.
