摘要
目的:应用定量组织速度成像技术(quantitative tissue velocity imaging,QTVI)所测Tei指数评价重度妊高征患者胎儿心功能的临床价值。方法:应用QTVI测量30例重度妊高征患者和60例正常孕妇胎儿右室房室瓣环室壁运动的射血期(ET)、等容收缩期(ICT)和等容舒张期(IRT)的时间间期,计算胎儿Tei指数。结果:重度妊高征组的IRT+ICT和Tei指数显著高于与对照组。结论:重度妊高征不仅对母体脏器造成危害,而且累及胎儿心脏功能。
Objective:To analyse ventricular function of fetuses with severe degree pregnancy induced hypertension (PIH) by quantitative tissue velocity imaging (QTVI). Methods:Using QTVI, the time interval of isovolumic relaxation time (IRT) + isovolumic contraclion time (ICT) and ejection time (ET) of fetuses were measured in 60 normal pregnancy womem in late pregnaney period and 30 patients with severe degree PIH. Tei index were calculated using the formula. Results:There were significant differences for Tel index of fetuses in two groups. Conclusion:PIH can decreased the ventricular function of the fetus.
