Abstract
Continuous and non-invasive measurement of blood pressure (BP) is of great importance. To achieve continuous and cuffless BP monitoring, pulse transit time (PTT) has been reported as a potential parameter. Nevertheless, this approach remains very sensitive, cumbersome and disagreeable for patients. This study proposes a new parameter available in phonocardiogram (PCG) to measure blood pressure. The PCG is processed and analyzed in order to measure the systolic and diastolic durations in order to study their correlation with an estimated PTT. The proposed approach evaluated on a developed data base of 37 subjects shows linear regression of two classes in distribution of diastolic duration with PTT estimated. Where, a good correlation coefficient is found for each class (class1: R = 0.87, class2: R = 0.85. This technic has significant potential to develop a new approach to measure blood pressure using PCG signal.
