超声心动图检测胎儿心律失常的临床诊断价值分析

Clinical diagnosis value of echocardiography in detecting fetal arrhythmia

目的探讨超声心动图在胎儿心律失常中的诊断价值。方法使用彩色多普勒超声仪探查胎儿心律及心脏结构,对比心律失常胎儿(50例,观察组)与健康胎儿(256例,对照组)超声心动图指标。结果观察组胎儿降主动脉、脐动脉、大脑中动脉指标与对照组比较差异有统计学意义(P<0.05)。观察组50例中期前收缩30例,心动过速10例,心动过缓6例,房室传导阻滞4例;心脏结构异常者6例。随访44例,39例预后良好,5例停止妊娠。结论超声心动图有助于早期发现心律失常及心脏结构畸形,为预后提供重要参考。

Objective To study the diagnosis value of echocardiography in detecting fetal arrhythmia. Methods The fetal heart rate and heart structure was detected by color Doppler ultrasound,the echocardiography indexes of the arrhythmia fetuses（ 50 cases,observation group） and of health fetuses（ 256 cases,control group） were compared. Results There were significant differences in the indexes of fetal umbilical artery,descending aorta,middle cerebral artery between the two groups. In the observation group,there were 30 cases of proiosystole,10 cases of tachycardia,6 cases with bradycardia,4 cases of atrioventricular block. Forty-four cases were followed-up,39 cases with good prognosis,5 cases stopped pregnancy; 6 cases lost follow-up.Conclusion Echocardiography contribute to early detection of arrhythmia and cardiac structural abnormalities,and provide important reference for prognosis.
