目的:探讨妊娠晚期孕妇心电图短P-R间期的临床意义及预后。方法:采用北京福田PI-18自动分析心电图机,对1 626例妊娠28~40周以上孕妇安静休息状态下以常规十二导联六道同步描记,由专业人员对每份心电图P-R间期进行测量。结果:妊娠晚期孕妇心电图短P-R间期的发生率(3.32%)远较高于正常人。结论:妊娠晚期孕妇出现短P-R间期现象,与旁路机制关系不大,而与交感神经兴奋性增强,自主神经功能紊乱等有关。
Objective: To investigate the clinical significance and prognosis of ECG in pregnant women of late pregnancy with short P-R interval. Methods: Using Beijing Futian PI-18 automatic analysis of electrocardiogram machine, 1 626 pregnant women over 28 to 40 weeks of pregnancy in resting state with conventional 12 lead six synchronous tracing, by professionals of each PR interval measurement . Results: The incidence of short P-R interval of pregnant women in late pregnancy (3.32%) was much higher than that of normal people. Conclusion: The pregnant women in the third trimester have a short P-R interphase, which has little to do with the bypass mechanism and is related to the enhancement of sympathetic nerve excitability and autonomic dysfunction.
