双多普勒超声在检测胎儿心律失常中的效果

The effect of double Doppler ultrasound in detecting fetal arrhythmia

目的探讨双多普勒超声在检测胎儿心律失常中的效果。方法选取我院2010年1月～2015年12月期间进行常规检查的35 760例胎儿,使用彩色多普勒超声检查,对于存在心率失常的86例胎儿应用双多普勒超声检查,同步记录降主动脉(DAo)和肝静脉(HV)血流频谱。结果 35 760例胎儿,使用彩色多普勒超声检查,共有86例心率失常胎儿,检出率为0.24%,对86例进行双多普勒超声检查,共70例存在心率失常,两组检查一致性较好,差异无统计学意义(P> 0.05);三种类型心率失常发生胎儿或母体疾病、胎儿宫内死亡或中孕引产例数构成比差异有统计学意义(P <0.05),其中慢速型心率失常转归情况最差。结论双多普勒超声对于不同类型的胎儿心率均能准确迅速诊断,其中不同类型的心律失常胎儿的预后情况有显著差异。

Objective To explore the effect of double Doppler ultrasound in detecting fetal arrhythmia.Methods35760fetuses who underwent routine examinations by color Doppler ultrasonography in our hospital from January2010to December2015were selected.Dual Doppler ultrasonography was performed in86fetuses with arrhythmia.The blood flow spectra of descending aorta(DAo)and hepatic vein(HV)were recorded simultaneously.Results In35760fetuses,86fetuses with arrhythmia were examined by color Doppler ultrasonography,the detection rate was0.24%.86cases underwent double Doppler ultrasonography,and70cases were examined arrhythmia.The consistency between the two groups was good,and the difference was not statistically significant(P>0.05).There were significant differences in the number of cases of fetal or maternal diseases,intrauterine fetal death or induced abortion among the three types of arrhythmia(P<0.05),among them slow arrhythmia had the worst prognosis.Conclusion Dual Doppler ultrasound can accurately and rapidly diagnose different types of fetal heart rate,and the prognosis of different types of fetal arrhythmia is significantly different.
