This paper presents a personal system and software architecture dedicated for cardiac telerehabilitation. The key idea of the hardware configuration and the software implementation is the integration of a mobile device and an ECG recorder with the application of wireless technologies: Bluetooth, GPS and GPRS. The main goal of the system is the reliable detection of the QRS complex providing a cardiovascular activity information to a cardiac telerehabilitation program. The prototype of the system allows the physician to construct a multistage training program, which can be divided into few levels. At each stage the supervising physician can customize parameters as: duration, speed, maximal and minimal heart rate. Additionally, a simple threshold-based alarm system has been implemented. The application of such monitors can reduce the costs and make the rehabilitation efficient, easier and allow an ubiquitous access.
