小儿预激综合征并发房室折返性心动过速药物复律效果回顾分析

目的探讨小儿预激综合征的临床特点及并发房室折返性心动过速的药物复律效果。方法回顾性分析山东省临沂市人民医院1997-01～2006-01住院并确诊为预激综合征患儿22例的临床资料。结果小儿预激综合征并发房室折返性心动过速，90．9％（20例）是顺传型，仅9．1％（2例）是逆传型，顺传型单用普罗帕酮转复率仅占56．3％（9／16），去乙酰毛花苷转复率可达到100％（10／10）。结论预激综合征并发房室折返性心动过速，若心电图为顺传型且用普罗帕酮无效时，则选用去乙酰毛花苷，若为逆传型，则可以选用普罗帕酮或胺碘酮。

Retrospective Analysis of curative effects of cardioversion drugs on atrioventricular reentrant tachycardia complicating pre.excitation syndrome in children

Objective To discuss clinical features of pre-excitation syndrome and curative effects of cardioversion drugs used in the treatment of atrioventricular reentrant tachy＇cardia complicating pre-excitation syndrome. Method Analyze the data of the children with pre-excitation syndrome who were admitted to our hospital over the past 10 years. Results In atriovantricular reentrant tachycardia, about 90. 9 % was of orthodromie conduction type,while 9.1% was of antidromic conduction type. About 56.3 % （9/16） children were interrupted by propafenone, while 100 % （10/10） were interrupted by cedilanid. Conlusions Cedilanid should be considered the drug of first choice for atrioventricular reentrant tachycardia in children whose electrocar-diogram（ECG）is of orthodromic conduction type and who don＇t react to propafenone,and propafenone or amioda-rone should be the first choice for antidromic conduction type.
