Abstract: 2003-01~2003-12门诊行胎儿超声心动图筛查孕妇3例,年龄23~38岁,孕龄20~40周。筛查采用Sequior—512型超声诊断仪,频率3.5MHz,4.0MHz;ATL3500超声诊断仪,频率3.5MHz。超声胎儿心脏检查内容包括探查胎儿内脏结构,二尖瓣、三尖瓣血流,主动脉口、肺动脉口血流,房间隔、室间隔穿隔血流,心率及节律。发现胎儿心动过缓时,取左室长轴切面彩色多普勒观察主动脉(或流出道)血流,然后将M型取样线,穿过主动脉(或流出道)和左心房后壁,记录出心房壁活动和左心室排出的彩色血流信号,观察到心房壁的活动及了解心室的收缩活动,以判断房室各自的活动规律及其相互关系。结果,3例
