In some cases of heart functional disorders, the heart might skip. The time of these dropouts might grow with the progress of the disease, and that can become dangerous. The monitoring, storing of heart rate, and signalling of disorders is a very important diagnostic task.

The purpose of this thesis is to design a device, that is capable of detecting the heart beats with an optical method, using a modern heart-rate monitor chip, measures the time between them with a microcontroller, stores these data, and if asked, transmits it to a computer. Besides, a simple model is designed, which is a non-portable, less complex realisation of the device, but it can serve the checking of functionality, and designing a prototype.

The thesis starts with an introduction, which is about the methods of heart measuring, and the comparison of them. After this, some often used modern chips are introduced, that are designed to detect heart beats with an optical method. The thesis demonstrates the designing of the said device, introduces the steps of designing, and the explanation of the important decisions. Then it shows the construction, functionality, and implementation of the microcontroller’s software.
