胎儿心律不齐的发生率约为1%,其中10%可能为胎儿病率的原因。过去对人类胎儿心血管系统的研究是通过间接的方法,即:母亲感到的胎动、胎心率听诊及胎心电子监测。现用超声检查胎心的解剖与生理;应用二维超声可评价胎心解剖结构,M型超声心动图用于了解胎心律、室壁、心腔大小和心包积液;多普勒超声心动图可检测各心腔和血管的血流速度;彩色多普勒血流标测可检出血流障碍,采集胎儿血可测血细胞计数、血气、血化学及药物水平。一、正常和异常心律
The incidence of fetal arrhythmia is about 1%, of which 10% may be the cause of fetal disease. In the past, studies on human fetal cardiovascular system were made through indirect methods, namely, mothers’ fetal movement, fetal heart rate auscultation and fetal heart rate monitoring. Fetal heart anatomy and physiology are examined with ultrasound; Fetal heart anatomy can be evaluated by two-dimensional ultrasound; M-mode echocardiography is used to understand fetal heart rate, ventricular wall, cardiac chamber size and pericardial effusion; Doppler echocardiography Figure can detect the heart chamber and blood vessels of blood flow velocity; color Doppler flow detection can detect blood flow disorders, fetal blood can be collected measurable blood cell count, blood gas, blood chemistry and drug levels. First, normal and abnormal heart rhythm
