胎儿心电图QRS波增宽的临床意义

Clinical significance of QRS prolongation fetal electrocardiogram

目的探讨胎儿心电图QRS波增宽的临床意义。方法对169例QRS波时限增宽孕妇与897例正常孕妇行胎儿心电图检查并进行比较,同时将前者结果与胎心率无负荷试验(NST)进行对比分析。结果 169例发生QRS波时限增宽者,胎儿宫内缺氧的发生与胎儿心电图正常比较,差异有统计学意义(P<0.05)。结论当FQRS时限增宽时胎儿出现宫内缺氧的发生率高,较NST检测有更高的敏感性与准确性。

Objective To evaluate the clinical significance of the fetal electrocardiogram QRS prolongation. Methods A total of 169 pregnancies with QRS prolongation and 897 normal pregnant women were all examined by fetal electrocardiogram, and the results were compared; meanwhile, the for- mer results were also compared with NST. Results There were significant differences in the incidence of fetal intrauterine hypoxia between 169 pregnant woman with QRS prolongation and 897 pregnant woman with normal fetal electrocardiogram（P 〈 0.01 ）. Conclusion When QRS duration was prolongated, the inci- dence of fetal intrauterine hypoxia was high. Compared with NST, the fetal electrocardiogram was with higher sensitivity and accuracy.
