After instrumentation and 10-minutes rest period, mental stress by operation was provided for 15-minutes. HRV was recorded before and after the mental stress. Then the control groups rested for 15-minutes. The experimental groups were treated with Aromatherapy. And then HRV was recorded.
Results : 1. There were no significant differences in the mean HRT and SDNN between each group. 2. LF, HF, and LF norm showed different changes in each group. 3. LF/HF ratio showed significant changes.
