观察妊娠期糖尿病(GDM)孕妇心率变异性(HRV)的改变。选取GDM孕妇30例作为GDM组,并与同期正常孕妇30例(非GDM组)及非妊娠妇女30例(非孕组)作为比较。前2组于孕32周及产后12周行24 h动态心电图检测;未孕组直接行24 h动态心电图检测。结果:GDM组及非GDM组在孕32周时的时域指标及频域指标中的总功率、高频谱功率、低频谱功率均低于非孕组(P<0.05),GDM组与非GDM组之间比较无差异(P>0.05);LF/HF值3组之间两两比较均无差异(P>0.05);GDM组及非GDM组产后12周的各项指标与非孕组之间比较均无差异(P>0.05)。结论:GDM对心脏自主神经系统功能影响小。
To observe the changes of heart rate variability (HRV) in pregnant women with gestational diabetes mellitus (GDM). Thirty patients with GDM were selected as GDM group and compared with 30 normal pregnant women (non-GDM group) and 30 non-pregnant women (non-pregnant group) during the same period. The first two groups in the 32 weeks of pregnancy and 12 weeks after delivery line 24 h dynamic electrocardiogram test; non-pregnant group directly 24 h Holter monitoring. Results: The total power, high-frequency power and low-frequency power of GDM group and non-GDM group at 32 weeks of gestation were lower than those of non-pregnant group (P <0.05) There was no significant difference between the two groups (P> 0.05). There was no significant difference in the LF / HF between the two groups (P> 0.05) There was no difference between the two groups (P> 0.05). Conclusion: GDM has little effect on cardiac autonomic nervous system function.
