摘要
目的分析产妇孕晚期和分娩后的心电图,了解分娩对女性心电图T波的影响。方法随机选取2018年2月至2018年4月在我院妇女保健科检查的226名产妇的临床资料,回顾其分娩前心电图,并与分娩后6～8周复查的心电图比较,观察T波的变化并分析分娩对T波的影响。结果分娩前,226名产妇的心电图异常主要为窦性心动过速、PR间期缩短;分娩后,多数产妇的窦性心动过速和PR间期均恢复正常,但窦性心动过缓和T波改变的例数明显增加。分娩后6～8周,产妇的窦性心动过速的发生例数明显减少,窦性心动过缓发生例数有所增加,PR间期缩短现象明显改善,T波异常者明显增多(P<0.05)。结论分娩后,产妇激素水平变化等因素会影响自主神经系统功能,导致心电图出现非特异性T波改变,临床应综合临床症状,随访心电图,保障母婴身心健康。
Objective To analyze the electrocardiogram in puerperas at late pregnancy and postpartum, and to understand the influence of delivery on T-wave of electrocardiogram in women. Methods The clinical data 226 puerperas from February2018 to April 2018 in the women's health department of our hospital were randomly selected. The electrocardiogram of puerperas before delivery were reviewed, and compared with the electrocardiogram reexamined at 6-8 weeks after delivery. The change of T-wave of puerperas before and after delivery were observed, and the influence of delivery on T-wave were analyzed.Results Before delivery, the main electrocardiographic abnormalities in 226 puerperas were sinus tachycardia and shortened PR interval; after delivery, the sinus tachycardia and PR interval of most puerperas returned to normal, but the number of puerperas with sinus bradycardia and T-wave changes increased significantly. At 6-8 weeks after delivery, the number of puerperas with sinus tachycardia decreased significantly, the number of puerperas with sinus bradycardia increased, the PR interval shortened significantly improved, and the number of puerperas with T-wave abnormalities increased significantly(P<0.05). Conclusion After delivery, changes in the levels of maternal hormone and other factors may affect the autonomic nervous system function, resulting in non-specific T-wave changes in electrocardiogram. Clinical symptoms should be synthesized and electrocardiogram should be followed up to ensure the physical and mental health of mothers and infants
