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 investigate the clinical significance of fetal ECG QRS broadening. Methods The fetal ECG of 169 pregnant women with QRS wave broadening and 897 normal pregnant women undergoing fetal electrocardiogram (ECG) examination were compared and compared. The results of the fetal ECG test were compared with the fetal heart rate without stress test (NST). Results Among the 169 patients with QRS wave broadening, the incidence of fetal hypoxia was significantly different from that of fetal electrocardiogram (P <0.05). Conclusion The fetus has a high incidence of intrauterine hypoxia when the FQRS duration is widened, which is more sensitive and accurate than the NST test.
