目的:本次研究主要探析M型与频谱及组织多普勒超声心动图联合使用在诊断胎儿心律失常中的临床诊断价值。方法:以本院2016年4月至2017年3月所接收的108例诊断疑似胎儿心律失常的孕龄为16-40周的孕妇为研究对象,对这108例研究对象使用M型、频谱以及组织多普勒超声诊断来确诊是否存在胎儿心律失常的症状。结果:所有研究对象在经过三种方法检查之后,共有46例孕妇被确诊为存在胎儿心律失常症状,确诊率42.59%。其中共有38例为期前收缩、2例心动过速、5例心动过缓以及1例房室传导阻滞。这46例存在心律失常胎儿中有3例胎儿合并先天性心血管畸形。结论:联合应用M型、频谱及组织多普勒超声诊断胎儿心律失常,通过M型、频谱多普勒、组织多普勒等技术进行检测,明确胎儿房室收缩与舒张的机械运动变化及其之间的关系来确定胎儿心律失常类型,以便于及早对存在心律失常的胎儿进行干预。 OBJECTIVE: This study mainly explored the clinical value of combined use of M-mode and spectral and tissue Doppler echocardiography in the diagnosis of fetal arrhythmia. METHODS: A total of 108 pregnant women with a gestational age of 16-40 weeks who had been diagnosed with suspected fetal arrhythmias received from April 2016 to March 2017 in our hospital were enrolled in this study. M-type, frequency spectrum and Tissue Doppler ultrasound diagnosis to confirm the existence of fetal arrhythmia symptoms. Results: After the three methods were examined in all the subjects, a total of 46 pregnant women were diagnosed as having fetal arrhythmia, the diagnosis rate was 42.59%. There were 38 cases of pre-contraction, 2 cases of tachycardia, 5 cases of bradycardia and 1 case of atrioventricular block. The 46 cases of arrhythmia fetus in 3 cases of fetal congenital cardiovascular malformations. Conclusions: Combined application of M type, spectrum and Tissue Doppler ultrasonography in the diagnosis of fetal arrhythmia, M type, spectral Doppler, Tissue Doppler and other techniques were used to detect the changes of fetal atrial contraction and diastolic mechanical movement and its To determine the type of fetal arrhythmia in order to facilitate the early intervention of the fetus with arrhythmia.
