自1978年3月～1982年12月,应用胎儿心电图仪进行了2002例分娩期监护。选择胎心率120～160次/分,胎龄37～42周,顺产且产后检查脐带羊水正常,而在分娩过程中胎儿心电图中 QRS 波群异常共73例进行观察和分析.其中27例来自正常妊娠组占2.05%,46例来自高危妊娠组占7.001%。73例 QRS 波群异常均伴有 QRS 波群时间延长,其类型为 Q 波异常2例,R 波有前顿挫12例,R 波有后顿挫36例,R 波多峰21例,S波异常2例。73例 QRS 波群异常中70例经处理生后短时间恢复正常,考虑系胎儿缺氧所致,余3例随访8月～2年仍显异常,考虑有先天性心脏发育异常的可能。
From March 1978 to December 1982, a total of 2,200 cases of childbirth were monitored with a fetal electrocardiograph. Select fetal heart rate 120 ~ 160 beats / min, gestational age 37 to 42 weeks, normal umbilical cord amniotic fluid and postnatal check normal, and in the process of childbirth fetal ECG QRS wave group abnormalities were observed and analyzed in 73 cases of which 27 cases from The normal pregnancy group accounted for 2.05%, 46 cases from high-risk pregnancy group accounted for 7.001%. 73 cases of QRS wave group were associated with prolonged QRS complex, the type of Q wave abnormalities in 2 cases, R wave anterior frustration in 12 cases, R wave thwarted in 36 cases, R wave multi-peak in 21 cases, S wave abnormalities 2 example. Seventy patients with QRS complex abnormalities returned to normal within a short period of time after treatment, accounting for the lack of oxygen in the fetus. The remaining three cases were still abnormal in the follow-up from August to February, and the possibility of congenital abnormalities of the heart was considered.
