| 目的：探讨胎儿出生前后左右心室收缩及舒张功能的变化。资料与方法：本文分析50例正常妊娠胎儿20～40周左右心室房室瓣口舒张期血流的A/E比值及主、肺动脉瓣口血流速度的变化, 同时比较14例足月妊娠与41例出生后新生儿的左右心室舒张收缩功能变化。结果：正常妊娠时, 随孕周的增加左右心室房室瓣口血流速度A/E比值逐渐降低, 主动脉及肺动脉瓣口收缩期血流峰速逐渐增加。胎儿出生后左心室舒张期房室瓣口血流速度A/E比值明显下降, 主动脉瓣口血流峰速明显增快右心室房室瓣口血流及肺动脉瓣口血流速度无明显变化。结论：正常妊娠期左右心室的舒张功能及收缩功能随孕周增加逐渐加强, 胎儿出生后左心室舒张功能及收缩功能明显加强, 而右心室舒张功能及收缩功能无变化。 |

| Pupose:To study the changes of left and right ventricular diastolic and systolic function between fetus and neonate.Materials and Methods:Blood flow velocity of mitral,tricuspid,aortic and pulmonary valve were measured in 50 fetus with normal pregnancy from 20 40 weeks and 41 normal neonate,A/E ratio in mital and tricuspid were calculated.Fetuses ventracular diastolic and systolic function were compared with that of neonate.Results:In normal pregnancy,blood flow velocity in mitral,tricuspid,arotic and pulmonary valve were continuous increased following pregnant weeks.A/E ratio in mitral were obviously decreased and blood flow velocity of aortic valve were significantly increases in neonate.Conclusion:After fetuses were birth,Left ventricular diastolic and systolic function were significantly increases,but right venticular disastolic and systolic function were not changed. |
