目的探讨妊娠期孕妇心电图短P-R间期的发生率及其与妊娠周数的相关性。方法选取我院2013年1月至2016年1月收治的600例接受常规心电图检查的女性为本次研究的对象,非妊娠的健康女性为对照组(250例),妊娠期孕妇为观察组(350例)。分析两组妇女的P-R间期发生率。同时将妊娠组女性按孕期长短分为三组,分别对各组短P-R间期的发生率进行对比分析。结果妊娠组心电图短P-R间期者发生率明显高于非妊娠组心电图短P-R间期者,两组对比差异具有统计学意义(p<0.05)。妊娠组孕晚期的妇女短P-R间期发生率与孕早期、孕中期的女性短P-R间期发生率有明显差异(p<0.05)。结论妊娠期妇女短P-R间期发生率比非妊娠健康女性有显著增高,而且,短P-R间期与妊娠周数呈正相关。
Objective To investigate the incidence of gestational ECG in pregnant women with short P-R interval and its correlation with gestational weeks. Methods A total of 600 women undergoing routine electrocardiography (ECG) from January 2013 to January 2016 in our hospital were selected as the study subjects. The non-pregnant healthy women were control group (250 cases) and pregnant women as observation group 350 cases). The incidence of P-R between the two groups was analyzed. At the same time, women in pregnancy group were divided into three groups according to the length of pregnancy. The incidence of short P-R interval in each group were compared. Results The incidence of electrocardiogram short-term P-R in pregnancy group was significantly higher than that in non-pregnancy group ECG P-R interval, the difference between the two groups was statistically significant (p <0.05). The incidence of short P-R in pregnant women in the third trimester of pregnancy was significantly different from that in the first trimester and the second trimester (p <0.05). Conclusions The incidence of short P-R interval in pregnant women is significantly higher than that in non-pregnant healthy women. Moreover, there is a positive correlation between short P-R interval and gestational weeks.
