Analyzing the acceleration photoplethysmogram (APG) is becom- ing increasingly important for diagnosis. However, processing an APG signal is challenging, especially if the goal is to detect its small com- ponents (c, d, and e waves). Accurate detection of c, d, and e waves is an important first step for any clinical analysis of APG signals. In this paper, a novel algorithm that can detect c, d, and e waves simul- taneously in APG signals of healthy subjects that have low amplitude waves, contain fast rhythm heart beats, and suffer from non-stationary effects was developed. The performance of the proposed method was tested on 27 records collected during rest, resulting in 97.39% sensitiv- ity and 99.82% positive predictivity.
