In this study, we propose a scheme to investigate the relationship between cognitive tasks and heart beat rate. Accordingly, a video focused on the face was recorded during a working memory experiment. Heart rate was noninvasively estimated from the camera recording. Subsequently, its spectral features were examined. These values were compared with heart rate dynamics obtained from a standard ECG. As a result of the comparison, we observed that the data from the video were compatible with the common heart r...

Spectral analysis of T wave alternans signal
Serinagaoglu, Y; Sabuncuoglu, D; Ider, YZ (1996-11-03)
T wave alternans signal was obtained from a patient who recently recovered from ventricular fibrillation. The power spectrum of the T wave alternans is computed using an Autoregressive model based technique. The signal is found to be a sinusoid at a frequency equal to the half of the heart rate and amplitude modulated with another sinusoid at a lower frequency. Relation between the spectrums of the T wave alternance signal and the RR variation signal is also discussed.
