摘要
目的探讨不同孕期异常心电图形的发生率及异常心电图形的分型与分布。方法随机入选206例无妊娠合并心脏病史的孕妇,作为观察对象,将其随机分为A、B、C三组。其中A组孕妇整个孕期常规进行一次心电图检查;B组孕妇于孕早、中期及32~34w常规进行两次心电图检查;C组孕妇于孕早、中期、32~34w及36~41w常规进行三次心电图检查,比较3组孕妇异常心电图形的发生率以及各孕期的异常心电图形变化。结果发现妊娠晚期异常心电图形的发生率比早、中期高,有统计学差异,但28~34-1w组与34~41w组比较,无统计学差异;且孕期进行两次或三次的心电图检查,比一次更能够及时发现妊娠期妇女的异常心电图变化,并且A组与B组或C组比较具有统计学差异。对孕28w之前分别与28w之后以及34w之后的孕妇异常心电图形进行比较,发现前者以窦性心动过速、后者则是以T波改变、窦性心动过速、窦速合并ST段改变具有统计学差异（p〈0.05或者p〈0.01）。结论妊娠晚期异常心电图形的发生率比早、中期高,但34w前后则无明显变化;重视妊娠晚期的心电图检查,有助于及时发现妊娠期妇女的异常心电图变化,且妊娠晚期异常心电图形以窦性心动过速居多;34w之后则是以T波改变、窦性心动过速、窦速合并ST段改变居多。
Objective To investigate the shape of pregnancy incidence of abnormal ECG and ECG abnormalities shaped type and distribution. Methods Randomly selected 206 cases of pregnant women with no history of heart disease in pregnant women, as the object of observation were randomly divided into A, B, C three groups. A group of pregnant women throughout pregnancy to conduct a routine ECG; Group B in pregnant women in early pregnancy, mid-week routine twice and 32~34 ECG; Group C of pregnant women in early pregnancy,mid-32~34 weeks and 36~41 weeks three routine ECG, abnormal ECG changes shape three groups of pregnant women, the incidence of abnormal ECG-shaped and each pregnancy. Results It was found late pregnancy incidence of abnormal ECG shape than the early and mid-high, a significant difference, but 28~34 and 34~41 weeks group group, no statistical difference; ECG during pregnancy and two or three times, more than once the ability to detect abnormal ECG changes in pregnant women, and the group A and group B or C group with statistical significance.Pregnant women before 28 weeks of pregnancy after 28 weeks, respectively, and 34 weeks after the abnormal ECG shape for comparison and found the former to sinus tachycardia, which is based on the T wave changes, sinus tachycardia, sinus tachycardia with ST segment changes with a significant difference（p〈0.05 or p〈0.01）. Conclusions late pregnancy incidence of abnormal ECG shape than the early and mid-high, but did not change significantly after34 weeks; attention late pregnancy ECG, ECG changes can help detect abnormalities in pregnant women, and abnormal ECG late pregnancy shape in the majority of sinus tachycardia; after 34 weeks is based on the T wave changes, sinus tachycardia, sinus tachycardia with ST segment changes majority.
