【摘要】 利用功率谱估计的方法 ,对 15例海洛因成瘾者和 15例正常人的 HRV信号进行分析。分析结果表明 ,在海洛因成瘾者和正常人心率变异性信号功率谱间存在高频谱峰位置的显著差异 ,即海洛因成瘾者 HRV信号功率谱的高频谱峰位于 0 .437± 0 .0 6 4Hz,而正常人的 HRV信号功率谱的高频谱峰位于 0 .32 5± 0 .0 5 2 Hz更多还原

【Abstract】 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.更多还原
