ABSTRACT:
A system for determining the heart rate in response to an electrocardiogram (EKG) signal that has been filtered by performing an autoregressive analysis, low-pass filtered by performing a digital filtering function, and the rate determined by utilizing a digital peak detection technique. In a heart rate detection system, the EKG signal from an EKG instrument is first digitized and then the colored noise component is removed from the digitized EKG samples by performing a linear predictive coding filtering function on the EKG samples. After the colored noise has been filtered from the digitized EKG samples, a low-pass filtering function is performed to remove high-frequency white noise by utilizing a digital finite impulse response filter. Finally, the heart rate is determined from the previously filtered EKG samples by a peak detection technique that performs a recursive algorithm to determine both the amplitude of the remaining peaks in the EKG samples and the period between these peaks.
