胎儿心电图对宫内缺血缺氧早期诊断的研究

Clinical Study of Fetal Electrocardiograph on Early Diagnosis of Intrauterine Anoxemia and Ischemia

胎儿宫内缺血缺氧是威胁胎儿生长发育及生命活动的重要原因之一。本文通过对１６４例经母体体表间接测出胎儿心电图的临床研究，不正常心电图５２例（占３１．７％），宫内缺氧及脐带因素为其主要原因。在各项异常心电图中，宫内缺氧可具有一项或两项以上异常，其中ＳＴ段改变更为敏感，应给予足够的重视，并积极治疗，以减少围产儿的窒息率，降低围产儿的死亡率。

The intrauterine anoxemia and ischemia have great adverse effect on the fetal growth and development, sometimes can even threaten the fetal life as a result of acute or chronic fetal distress. A total of 164 3-rd trimester pregnant women receiving indirect maternal percutaneous FECG measurement were studied. There were abnormal FECG in 52 cases(31.7%).The intrauterine anoxemia and umbilical cord factor are the main causes of the abnormal FECG. The intrauterine anoxemia might present one or more abnormal manifestations, such as heightened amplitude of the QRS wave, tachycardia or bradycardia, elevated or depressed S-T segment and so on, among which the S-T changes are more sensitive. The sufficient attention to anoxemia and ischemia should be paid and more active treatment should be given in order to reduce the perinatal asphyxia and mortality of the newborn.
