| Abstract | To assess the modifications of the sympatho-vagal balance induced by mental stress, we have accomplished a computerized system able to cany out a complete spectral analysis of heart rate variability (HRV) signal. Based on a personal computer, it acquires ECG, respiratory, and blood pressure signals for each step of a mental stress trial. The collected data are then processed and spectral analysis is carried out by conventional FFT; besides, an autoregressive (AR) identification algorithm, computes the power and the central frequency of the spectra peaks, allowing automatic classification of Low Frequency (LF) and High Frequency (HF) peaks. The analysis executed for each step of the trial allows the comparison of the various spectral responses corresponding to different stimulations. We tested this system on 32 recently infarcted subjects and results show a significant increment in LF peak (P<0.005) and a significant reduction in HF peak(P<0.05), during mental arithmetic task. Our preliminary results suggest that this method of spectral analysis of HRV signal can be considered a useful technique to evaluate the autonomic response to mental stress. |
