Abstract: Heart rate is very important physiological parameter that is directly concerned with the soundness of human cardiovascular system. The condition of the cardiovascular system is examined by haemodynamic measurements and by recording the electrical activity of the heart and heart sound. To estimate the performance of the heart as a pump, measurement of cardiac output, blood pressure, blood volume are important and it is carried out in various ways throughout the circulatory system. This paper describes the noninvasive technique to measure the variation in the blood volume in tissue using a pulse sensor which contains a light source and a detector. As the change in blood volume is related to simultaneous occurrence the heart beat, this method can be used to calculate the heart rate.
