Abstract： 目的探讨超声心动图检测对胎儿心律失常的诊断价值及临床意义.方法采用超声心动图对725例胎龄16～41周临床疑诊为心律失常或存在其他异常的胎儿进行检测.结果共检出胎儿心律失常90例. 其中,期前收缩72例(房性期前收缩65例,室性期前收缩7例),心动过缓9例,心动过速6例, 2∶ 1房室传导阻滞2例,心房扑动1例.4例心动过缓胎儿并发先天性心血管畸形患者,2例在随访过程中死于宫内(尸体解剖证实为单心室伴肺动脉瓣狭窄1例,心脏横纹肌瘤1例),2例终止妊娠(尸体解剖证实为二尖瓣闭锁1例,共同房室通道1例).1例胎龄38周心房扑动胎儿经吸氧及严密监护24 h后,心律失常无缓解,立即行剖宫产术,出生后应用西地兰后心律转为窦性.其余85例胎儿心律失常均为阵发性,不伴有胎儿心脏形态、结构畸形及胎儿水肿,均足月出生,出生后听诊均未闻及心脏杂音及心律失常.结论胎儿超声心动图是产前检查胎儿心律失常的可靠的无创性影像技术,其应用有助于早期检出并指导心律失常胎儿的处理.
