Abstract: AbstractObjectiveAnalyzing the clinical characteristics and the treatment in 17 children with complete atrioventricular block (CAVB) resulted from the infectious myocarditis. MethodsFrom Aug.1984 to Mar.2005,17 cases of CAVB resulted from the infectious myocarditis were reviewed. ResultsOf the 17 children reviewed,8 had AdamsStoke syndrome and 5 had heart failure;13 of them had cardiomegaly on chest xray.The echocardiography in 13 cases all showed left ventricular enlargement.The average ventricular rate on electrocardiogram was (528±104)/min.Six patients with the fulminant myocarditis were given the methylprednisolone and medication for protecting the damaged myocardium.Three patients were given emergence temporary pacing.The rest children were given the medicine for improving conduction.In this group,6 patients were cured,and 5 patients showed clinical improvement,but 5 patients still showed CAVB and 1 patient died. ConclusionCAVB associated with acute myocarditis may be lifethreatening;if the patients are diagnosed early enough and are given large doses of the adrenal cortical hormone in time and administered emergence temporary pacing,the prognosis will be much better.On the other hand,if atrioventricular block occurs on followup,bundle branch block appears and QRS widens with the nodal escape,the diease may progress to CAVB.
