妊娠期高血压对心室复极的影响
Impact of hypertensive disorder in pregnancy on ventricular repolarization
【摘要】 目的分析妊娠期高血压疾病患者体表心电图的心室复极指标,探讨其对心室复极的影响。方法选择2009年4月—2011年4月收治的324例孕妇作为研究对象,根据是否患有妊娠期高血压疾病分为高血压组和正常组各162例。两组均于入院第1天接受心电图检查,分析和比较两组ST-T段、QT间期、QTc等心室复极指标。计量资料采用t检验,计数资料采用χ2检验,P<0.05为差异有统计学意义。结果高血压组ST-T段异常63例,占38.89%;正常组32例,占19.75%,差异有统计学意义(P<0.05)。高血压组QT间期为(323.8±17.1)ms,低于正常组的(355.5±15.7)ms,差异有统计学意义(P<0.05)。高血压组QTc为(444.2±19.3)ms,高于正常组的(428.4±28.4)ms,差异有统计学意义(P<0.05)。结论妊娠期高血压疾病影响心室正常复极,并使心室复极时间延长。
【Abstract】 Objective By analyzing ventricular repolarization indexes of the surface ECG in patients with hypertensive disorder in pregnancy,to investigate its effects on ventricular repolarization. Methods 324 pregnant women from April 2009 to April 2011 were selected,randomly divided into hypertension group(162 cases) and normal group(162 cases). Analysis and comparison the indicators of ventricular repolarization between two groups,including ST- T segment,QT interval,QTc. Count data was processed by t- test,measurement data by chi- square test,P < 0. 05 was considered statistically significant. Results The number of cases whose ST- T segment is abnormal in hypertension group was 63( 38. 89%),in normal group was 32(19. 75%),difference was significant( P < 0. 05). The QT interval in hypertension group was(323. 8± 17. 1) ms,higher than that in normal group(355. 5 ± 15. 7) ms,difference was significant( P < 0. 05). The QTc in hypertension group was(428. 4 ± 28. 4) ms,longer than that in the normal group(444. 2 ± 19. 3) ms,difference was significant(P < 0. 05). Conclusions Hypertensive disorder complicating pregnancy affect the ventricular normal repolarization and prolong the time of ventricular repolarization.
