    【摘要】目的：探讨超声心动图研究妊娠期和产后母体肺动脉血流量、左房容积指数的变化。方法：研究选取2017年1月—2021年6月期间在本院建档就診的40例单胎初产孕妇作为研究对象，分成非妊娠组(计划妊娠期)、妊娠组(妊娠32～24周)和产后组(产后8～12个月)。使用EPIQ 7C超声诊断仪分别测量三组研究对象的肺动脉血流量、左心房容积指数超声心动图指标，对比分析非妊娠组、产后组及对照组之间的肺动脉血流量、左心房容积指数的变化，评价妊娠对母体心脏的影响。结果：妊娠组肺动脉血流量增多、左心房容积指数增加，与非妊娠组、产后组比较有统计学差异(P0.05)。 结论：妊娠期肺动脉血流量及左心房容积指数增加，产后恢复正常水平，这种变化为妊娠期特有的生理性可逆过程，对母体病理性妊娠的更进一步研究起到了更好的铺垫作用。
