Abstract
We proposed an adaptive pulse template method for accurate detection of heart beat from pressure signals measured during sleep. 13 subjects´ pressure and photoplethysmography signals were measured during sleep for evaluation. Compared with our previous heart beat detection method based on differential filtering, the adaptive pulse template method has a higher positive predictivity 94.46% and a satisfying sensitivity 94.08% for the detection of heart beat in the pulse waveform extracted from pressure signals. The accurate detection of heart beat can improve the estimation accuracy of pulse rate variability analysis.
