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.
