A Study on the Relation between Anemia and Heart Rate Variability in Postpartum Women

산모에서 빈혈과 심박변이도의 관계 연구

Purpose : This research was designed to determine whether HRV can be used as an assessment index in weakly postpartum women. Methods : The subjects were 232 women who admitted for postpartum care in Oriental Hospital of Woosuk University from 19, December 2005 to 21, July 2006. They took the test of CBC and HRV. And then we selected 200 cases of postpartum women. The SPSS 10.0 for windows was used to analyse the data and the simple correlation coefficient and the independent samples t-test were used to verify the results. Results : The following results were obtained : 1. There were positive correlations between items of CBC(RBC, Hb, Hct) and SDSD, RMSSD, SDNN, and also between items of CBC and log-transformed index of spectral analysis. There were negative correlations between items of CBC and Mean-HRV, pNN50. 2. SDNN of anemic postpartum women group significantly decreased compared with that of normal postpartum women group. HRV-Index, RMSSD and SDSD of anemic postpartum women group significantly decreased compared with that of normal postpartum women group. pNN50 of anemic postpartum women group significantly increased compared with that of normal postpartum women group. 3. Ln(TP), Ln(VLF), Ln(LF) and Ln(HF) of anemic postpartum women group significantly decreased compared with that of normal postpartum women group. Conclusion : The results suggest that the function of heart of anemic postpartum women group significantly decreased compared with that of normal postpartum women group.
