目的探讨心率变异性（ＨＲＶ）对妊娠合并器质性心脏病患者发生心功能衰竭的预测价值。方法对６１例妊娠合并器质性心脏病患者，分别于妊娠２８～３２周及分娩后７天进行动态心电图及心率变异性的测定。结果９例患者发生心功能衰竭，以未发生心功能衰竭者作为对照进行比较，发现心功能衰竭患者心率变异性时域指标明显下降，差异有显著性（Ｐ＜０．０５）。分娩后７天，当心功能衰竭患者一般状况得到改善后，心率变异性标准差均值、平均Ｒ－Ｒ间期标准差之标准差值上升（Ｐ＜０．０５）。结论心率变异性对判断心脏储备力，预测妊娠期心功能衰竭的发生具有一定的价值
Objective To investigate the predictive value of heart rate variability (HRV) for heart failure in patients with pregnancy complicated with organic heart disease. Methods 61 cases of pregnancy complicated with organic heart disease were measured at 28 to 32 gestational weeks and 7 days after childbirth to measure the dynamic electrocardiogram and heart rate variability. Results Nine patients had heart failure, and those who did not have heart failure were compared. The time-domain index of heart rate variability was significantly decreased in patients with heart failure (P <0.05). At 7 days after delivery, the standard deviation of the standard deviation of the heart rate variability and the standard deviation of the mean R-R interval increased (P <0.05) after the general condition of patients with heart failure improved. Conclusion Heart rate variability has some value in judging heart reserve and predicting the occurrence of heart failure during pregnancy
