Purpose: This study was performed to find correlations between Edema Index and Heart Rate Variability(HRV) conducted in early postpartum period. Methods: 17 postpartum women were participated in this study which was conducted with Inbody 720(Biospace Co. Ltd.) and SA-6000(Medicore Co. Ltd.). Edema Index(Extra Cellular Water/Total Body Water) was calculated after body composition analysis and HRV result(TP, VLF, LF, HF, HF norm, LF norm, LF/HF ratio) was analysed within a week after delivery. Results: There was no significant correlations between Edema Index and HRV results in time domain analysis. also Edema Index and TP, LF, HF, LF/HF ratio have no significant correlations in frequency domain analysis. but only VLF data has significance compared with Edema Index. Conclusions: It can be suggested that VLF results analysed by HRV can be useful reference estimating postpartum edema especially occurs in early postpartum period.
