Abstract：Objective To analyze chnical characteristics,treatments and outcomes of complete atrioventricular block (CAVB) in children.Methods Clinical records of 78 children with CVAB who were admitted from 2007 to 2015 at Beijing Children's Hospital,Capital Medical University were retrospectively analyzed.Results Thirty children had congenital CAVB;the median age was 2.2 years(3 d-9 years);3 of them had permanent pacemaker implantation and recovered well;temporary pacemaker in 2 cases and symptomatic drug therapy(gamma globulin,hormone and cardiac muscle nutritional drugs) in 25 cases showed no positive effect.Thirty-six children had acquired CAVB;the median age was 4.0 years(1 months-14 years);among 19 infectious myocarditis,8 cases with temporary pacemaker implantation and 1 case with permanent pacemaker implantation recovered,4 in 10 cases with drug therapy recovered;15 children developed CAVB after surgery or interventional procedure,6 of them treated by permanent pacemaker implantation and 2 in 4 cases treated by permanent pacemaker implantation recovered,5 cases treated by drug therapy showed no obvious improvement;1 child with rheumatic heart disease and 1 child with anaphylactic shock were improved by drug therapy.Twelve children were not defined the cause of CAVB;the median age was 5.9 years(5 months-11 years);1 case with permanent pacemaker recovered;1 case with temporary pacemaker and 10 cases treated by symptomatic drug therapy showed no improvement.Conclusion Drug therapy has no obvious effect on congenital CAVB but it is effective for acquired CAVB;pacemaker implantation should be performed when drug therapy is not effective.
