Abstract: Pulse transit time is considered as a vital physiological parameter for assessing several cardiac disorders. It was proven that pulse transit time provides accurate diagnosis in estimation of blood pressure. In this paper, we demonstrate an instrumented hardware for the development of reflectance photoplethysmograph. The designed system uses two reflectance sensors at two different arterial locations for the estimation of pulse transit Time. Developed hardware is used for the calculation or estimation of the pulse transit time from the two photoplethysmograph signals obtained, one from the wrist and the other from the finger respectively, estimated pulse transit time is compared against the gold standard equipment, the results indicate the estimated values are within the limits of medical diagnostic values.
