Abstract: This study describes the development of a heart rate control system based on a microcontroller. It offers the advantage of portability over tape-based recording systems. The study explains how a single-chip microcontroller can be used to analyse heart beat rate signals in real-time. In addition, it allows doctors to get the heart beat rate file of the patient by e-mail every twenty four hours. It can also be used to control patients or athletic person over a long period. The system reads, stores and analyses the heart beat rate signals repetitively in real-time. The hardware and software design are oriented towards a single-chip microcontoller-based system, hence minimizing the size. The important feature of this study is the use of the zero crossing algorithm to compute heart rate. It then processes on real-time the information to determine some heart diseases.
