In this paper, the method of power spectral estimation is used to analyze the heart rate variability (HRV) signals for 15 heroin addicts and 15 healthy persons. The analysis result shows that there is a significant difference of the locations of the high-frequency peaks between the power spectra of heroin addicts\' HRV signals. It means that the locations for heroin addicts lie in 0.437 +/- 0.064 Hz and the locations for healthy persons lie in 0.325 +/- 0.052 Hz.
