Applying the APG to measure Heart Rate Variability

The Acceleration Plethysmogram (APG) is used to calculate the heart rate (HR) and HRV. The APG is an optical technique that has been developed for experimental use in vascular diseases. It is considered a promising tool that may replace some of the current traditional cardiovascular diagnostic tools. The performance of the proposed algorithm when tested on 26 records measured at rest showed very promising results. Our results demonstrate that the HRV indices, SDNN and rMSSD can be calculated using APG signals collected at rest.
