摘要 目的探讨妊娠晚期(28~41周+6)正常胎儿左、右心室Tei指数的参考范围,为临床应用提供理论依据。方法应用多普勒超声心动图测量120例妊娠28~41周+6胎儿左、右心室的射血时间、等容收缩及舒张时间,计算左、右心室Tei指数,并分析与孕周的相关性。结果妊娠晚期正常胎儿左心室平均Tei指数为0.427±0.187,右心室平均Tei指数为0.416±0.161,两者比较,差异无统计学意义(P〉0.05);不同孕周胎儿Tei指数比较,差异无统计学意义(P〉0.05)。胎儿左、右心室Tei指数呈正相关(r=0.553,P〈0.001)。结论 Tei指数不受孕龄的影响,可用于观察各种情况下的胎儿整体心功能变化。
