妊娠期心电图改变及临床分析

The changes of electrocardiogram and clinical management in pregnancy woman.

目的进一步了解妊娠期心电图变化,探讨其临床意义及相应处理。方法回顾性分析2921例妊娠期妇女心电图检查结果及相关资料,按妊娠早中期及晚期进行分组,并对其中的异常心电图进行分类比较。结果在妊娠晚期、心电图异常的发生率显著高于妊娠早中期(分别为38.20%,23.92%,P<0.01),主要表现为窦性心动过速,P-R间期缩短、电轴左偏、ptfV1≤-0.04mm/s以及左室肥厚。结论妊娠期较早中期更易出现心电图的异常,其中部分与妊娠的生理变化相关,通常无须特殊的临床治疗,而地于并发于器质性心脏病患者的异常心电图,需根据具体情况给予适宜的处理。

Objective To further understand the common changes and clinical significance of electrocardiogram in diffemt stage of pregnancy, and thus take appropriate measures to treat. Methods Total 2921 cqpies of electrocardiograms from the early/middle-or late-stage pregnant women were retrospectively analyzed. The abnormal changes of electrocardiograms were further classed and compared. Results The incidence of abnormal electrocardiogram in the late-stage was significantly higher than that in the early/middle-stage pregnancy （ 38.02 %, 23.92 %, respectively, P 〈 0.01 Among them, the most common changes included sinus taehycardia, short P-R interval, left axis deviation, ptfV1≤ - 0.04mm/s and left ventficular hypertrophy. Conclusion Electrocardiographic abnormality appears more frequent in the late-stage than that in the early/middle-stage pregnancy. Part of them were associated with physiological changes of gestation and ned not undergone particular treatment. However, effective measures should be taken for part of abnormal electrocardiogram which is complicated with organic heart diseases on the basis of clinical condition.
