Heart related diseases are increasing day by day and there is a need for an accurate and affordable heart rate monitoring system for diagnoses. However, most heart rate measuring paraphernalia and environments are expensive and do not follow ergonomics. The proposed Heart Rate Measuring (HRM) system is economical, user friendly and uses optical technology to detect the flow of blood. The system is designed to sense and measure the pulse by clipping sensors on one of the fingers and then displaying the result on an Organic Light Emitting Diode (OLED) and synchronized with a software application at the medical personnel side. The paper explains how a single-chip microcontroller can be used to analyze heart beat rate signals in real-time and provide the information of bradycardia and tachycardia of heart rates, logged the details at interval and broadcast the information to the medical personnel if the heart rate exceeds the threshold. Qualitative and quantitative performance evaluation of the device on real signals shows accuracy in heart rate estimation. This system can be employed in the hospitals/clinics/ research and medical centers especially in developing countries to reduce the rate of death caused by cardiovascular related diseases.
