METHODS OF MEASURING THE DEGREE OF SUBJECTIVE DEPRESSION BY USING HF

摘要

The present invention relates to a method to measure a subjective depression degree by using an HF. The method includes: a step (1) of receiving an electrocardiogram (ECG) signal for a preset time; a step (2) of converting the received signal into heart rate variability (HRV); a step (3) of measuring a high frequency (HF), which is a 0.15-4 Hz component obtained from the converted HRV through spectrum analysis; and a step (4) of determining a higher subjective depression degree as the measured HF value gets smaller than an average value by comparing the HF value to the average value in a comparison group. The present invention is capable of objectively evaluating a subjective depression degree of a general person, and using the same as an objective index for a large scale stress selection test or mood disorder high-risk group selection test.
