Abstract

The purpose of this study is looking for deviation of change in HRV caused of posture. Total 20 adults were measured for 40 minutes(10 minutes rest section and 30 minutes analysis section) when volunteers were sitting and lying down. Other factors which can change in HRV were controlled during measurement. The analysis section were divided by total 6 stages(each by 5 minutes), and compared and analyzed between sitting and lying down groups. It was also compared and analyzed stages in each group. In the result, there was difference at stage 5($20{\sim}25$ minutes interval), but no difference in the total data. The results of each stage in the group, lying down had difference. Therefore, sitting is more stable measurement for HRV study when subjects was waking over 15 minutes.
