Design and Implementation of an Embedded System for Ambulatory Cardiac Monotoring

Cardiac monitoring in the environment of the subject is one of the major fields of telemedicine. In this paper, we present a prototype of embedded system for acquisition, storage, display on LCD or PC and transfer via GSM alarm warning in case of arrhythmias, which allows a great opportunity for rapid intervention of the physician. In terms of hardware, we have designed and implemented our system with a modular approach to facilitate development and debugging. Thus the system comprises three modules: analog module, digital module based micro controller for certain pretreatment, and a GSM communication module. Of course, there is appropriate software behind the material described. The system has the following features: low cost, easy to use and versatile.
