Objective To explore the pathogenesis,clinical symptom,therapy and prognosis of complete atrioventricular block(CAVB) in children.Methods The clinical data of 53 children with CAVB who were diagnosed in the past 5 years were reviewed,the patients were divided into congenital CAVB group and acquired CAVB group,and they were treated with different protocol based on clinical symptoms,consulted on the guideline for implanting pacemaker(PM) respectively.The prognosis was recorded.Results Eleven patients were in congenital CAVB group,5 cases of them had Adams-Stokes′s syndrome as first onset and the others were diagnosed as arrhythmia in physical examination.Forty-two patients were in acquired CAVB group,32 cases of them were postoperative of congenital heart disease,most disease were ventricular septal defect,double outlet of right ventricle and corrected transposition of great arteries.Eight patients were diagnosed as severe myocarditis,2 cases of them had dyspnea and chest pain,4 cases had vomiting and diarrhea,and 2 cases had cough and nasal discharge.Six patients with congenital CAVB implanted permanent PM,4 cases were in following up.One of patients implanted PM had heart failure 4 years later.Eighteen patients with acquired CAVB implanted PM,1 case of double outlet of right ventricle died of pacing failure 5 years after procedure.Conclusions Some of children with congenital CAVB should be implanted permanent PM;however,children with acquired CAVB should be emphasized to treat primary disease and few of them should be considered to implant PM,even though that was a safe and effective therapy to CAVB,the complication of PM should be considered when following up.
