胎儿心电图在高危妊娠诊断中的临床意义

The clinical significance of fetal electrocardiogram in the diagnosis of high-risk pregnancy

目的：探讨胎儿心电图在高危妊娠诊断中的临床意义。方法：选择孕32~42周的高危妊娠孕妇130例和相同孕周的正常孕妇60名（对照组）进行胎儿心电图检查,对胎儿心电图结果进行比较分析。结果：高危妊娠组胎儿心电图异常发生率为49.23%,明显高于对照组的11.67%（P〈0.01）。高危妊娠组胎儿心电图异常表现主要为心动过速（42.19%）、ST段改变（18.75%）、心律不齐（17.19%）和心动过缓（15.63%）,但2组胎儿异常心电图构成差异无统计学意义（P〉0.05）。结论：高危妊娠孕妇定期检测胎儿心电图可早期发现胎儿宫内窘迫、缺氧,对降低新生儿窒息发生率及病残儿出生率有重要临床价值。

Objective： To investigate the clinical significance of fetal electrocardiogram in the diagnosis of high-risk pregnancy.Methods： The fetal electrocardiogram in 130 high-risk pregnant women with 32 to 42 gestational weeks and 60 normal pregnant women with the same gestational age were examined,the result of which was analyzed. Results： The incidence of abnormal fetal electrocardiogram in high-risk pregnant women（ 49. 23%） was significantly higher than that in normal pregnant women（ 11. 67%）（ P〈0. 01）. The main manifestations of abnormal fetal electrocardiogram were tachycardia（ 42. 19%）,ST segment change（ 18. 75%）,arrhythmia（ 17. 19%） and bradycardia（ 15. 63%）,the composition difference of abnormal fetal electrocardiogram in all cases was not statistically significant（ P〉0. 05）. Conclusions： The periodic testing of fetal electrocardiogram in high-risk pregnant women can early find the fetal distress and hypoxia,reduce the incidence of neonatal asphyxia,and reduce the birth rate of disabled children.
