摘要 目的探讨儿童室性心律失常发生与T波电交替(TWA)改变的关系。方法比较室性心律失常运动试验阳性和阴性患儿,以及与正常对照儿童之间持续TWA发生率、持续TWA发生的心率阈值和心率阈值/极量心率的差异。结果运动试验阳性与阴性患儿的持续TWA发生率均明显高于正常对照儿童,持续TWA发生的心率阈值和心率阈值/极量心率明显低于正常对照儿童,差异均有统计学意义(P<0.05)。运动试验阳性与阴性患儿比较,其持续TWA发生率明显增高,持续TWA发生的心率阈值和心率阈值/极量心率明显降低,差异均有统计学意义(P<0.05)。结论持续TWA与儿童室性心律失常密切相关。 Objective To explore the characteristics of T wave alternans(TWA)in children with ventricular arrhythmias.Methods The incidence of sustained TWA,onset heart rate threshold and heart rate threshold/predicted maximum heart rate were compared in normal control group,positive treadmill test group and negative treadmill test group with ventricular arrhythmias.Results Compared with normal group,the incidence of sustained TWA was significantly increased,and onset heart rate threshold and heart rate threshold/predicted maximum heart rate were significantly decreased in both of treadmill test positive group and negative group with ventricular arrhythmias(P < 0.05).The incidence of sustained TWA was higher and onset heart rate threshold and heart rate threshold/ predicted maximum were significantly lower in treadmill test positive group than in negative group(P < 0.05).Conclusions Sustained TWA is closely related to ventricular arrhythmias in children.
