正常孕妇的心率变异性及室性心率失常的分析

目的:为观察正常孕妇的心率变异性(HRV)以及室性心律失常的发生,探讨孕妇心脏自主神经功能的平衡情况。方法:对89例孕妇和正常未孕妇44例进行24 h的室性心律失常(VA),对其时域、频域结果进行分析。结果:与对照组相比,怀孕各组大部分时域、频域指标均明显降低(P<0.05),但与妊娠周数无关;而怀孕伴VA与怀孕无VA,HRV比较有显著性差异(P<0.05)。结论:提示怀孕伴VA可能与心脏自主神经功能失衡有关,HRV分析对临床评价孕妇自主神经功能有一定的参考意义。

Analysis on heart rate variability and ventricular arrhythmias in normal pregnant

Objective:To investigate the heart rate variability(}tRV)and occurrence of ventricular arrhythmias in normal pregnant woman and to explore the balance of autonomic nervous function.Methods:24h ambulatory electrocardiography were performed in 89 pregnant women and 44 healthy controls.We observed ventricular arrhythmias in 24h and analyzed 24h time-domain and frenquency-domain.Results: Most of time-domain and frenquency-domain decreased in guoup pregnancy compared nith the contral group(P<0.05),but there were no relation between HRV and pregnant week.There were significant differences between the group of pregnancy with ventricular arrhythmias and without ventricular arrhythmias(P<0.05).Conclusions: The pregnancy nith ventricular arrhythmias may be related nith balance reduction of autonomic nerrous function.Heart rate variability has reference.Significance for assessment cardiovascular autonomic function in pregnant women.
