Abstract :
The authors computed the discrete Wigner distribution (DWD) of the instantaneous heart rate for six male subjects. The power of the ventilation frequency decreased during the segment of the experimental protocol that included no breathing. Parameters extracted from the time-frequency distribution corresponding to respiratory sinus arrhythmia may be useful in conjunction with a typical apnea detection algorithm that is prone to false alarms due to movement artifacts in the ventilation signal
