妊娠中晚期孕妇120例动态心电图检测及妊娠结局分析

Dynamic Electrocardiogram Detection and Pregnancy Outcome Analysis of120 Pregnant Women in Middle and Late Pregnancy

目的探讨妊娠中晚期孕妇动态心电图特点及对妊娠结局的影响。方法方便选择2017年3月—2018年3月该院收治的240例中晚期孕妇为研究对象,按照随机数表法分为观察组和对照组,各120例。对照组给予常规心电图(ECG)检测,观察组给予动态心电图(DCG)检测,记录孕妇异常心电图例数,对检测结果异常的孕妇进一步治疗,评价并分析孕妇的妊娠结局。结果观察组(DCG)孕妇异常心电图例数检出率(44.2%)明显高于对照组(ECG)异常检出率(16.7%),两组比较差异有统计学意义(χ~2=21.438 8,P<0.05)。心律失常类型中,观察组主要表现为窦性心律不齐、短阵房速明显高于对照组,两组比较差异有统计学意义(P<0.05)。经过对异常心电图孕妇采取进一步治疗后,观察组发生流产、剖宫产、早产、低体重儿、新生儿窒息等不良妊娠结局的发生率(14.2%)明显低于对照组(28.3%),两组比较差异有统计学意义(χ~2=11.273 3,P<0.05)。结论动态心电图应用于妊娠中晚期孕妇,检出率高更易采取进一步治疗措施,提高围生儿质量,改善妊娠结局。

Objective To investigate the characteristics of dynamic electrocardiogram in pregnant women in the second trimester of pregnancy and their effects on pregnancy outcomes. Methods Convenient select a total of 240 middle-and late-stage pregnant women admitted to our hospital from March 2017 to March 2018 were enrolled in the study. According to the random number table method, they were divided into observation group and control group, 120 cases each. The control group received routine electrocardiogram(ECG) test, the observation group was given dynamic electrocardiogram(DCG)test, the number of abnormal electrocardiograms in pregnant women was recorded, and the pregnant women with abnormal test results were further treated, and the pregnancy outcome of pregnant women was evaluated and analyzed. Results The detection rate of abnormal electrocardiogram(44.2%) in the observation group(DCG) was significantly higher than that in the control group(ECG)(16.7%). The difference between the two groups was statistically significant(χ^2=21.438 8, P<0.05).Among the arrhythmia types, the observation group mainly showed sinus arrhythmia and short-term atrial tachycardia significantly higher than the control group. The difference between the two groups was statistically significant(P<0.05). After further treatment of pregnant women with abnormal electrocardiogram, the incidence of adverse pregnancy outcomes(14.2%)such as abortion, cesarean section, premature delivery, low birth weight, and neonatal asphyxia were significantly lower in the observation group than in the control group(28.3%). The difference between the groups was statistically significant(χ^2=11.273 3, P<0.05). Conclusion Dynamic electrocardiogram is applied to pregnant women in the middle and late pregnancy.The detection rate is higher and it is easier to take further treatment measures to improve the quality of perinatal children and improve pregnancy outcomes.
