Using a wearable electrocardiograph with three accelerometers which we developed, ECGs of subjects were measured for analysis of a short term and long term change of autonomous nerve activity in daily life. An electrocardiogram and acceleration data of each subjects were measured, and time series data of an autonomous nerve activity index were analyzed with heart rate variability (HRV) power spectrum analysis continuously. As a result of most subjects, circadian rhythm of the night and day of autonomous nerve activity was observed. However, some analyses results of exceptional rhythm of subjects were observed. This paper reports these analysis results with subjectivity evaluation. |
