Abstract

Design and realization of a wireless PC-based system for electrocardiography and data acquisition of a patient's heart condition is described in this paper. The system is designed and realized according to virtual instrumentation concept consisting of two subsystems: 1) The battery powered external compact and mobile wireless ECG acquisition hardware on the side of patient and USB connected communication wireless module on the PC side; 2) Standard personal computer with graphical user interface and database support. The USB port is selected to be the communication interface between the ECG acquisition hardware and the PC and also to supply power to the communication wireless module at the PC side. The Graphical User Interface (GUI) is designed in the traditional style of ECG paper plots and additional displays based on suggestions of cardiologists. Strict medical requirements are respected in the design of the system.

Key words: ECG, virtual instrument, wireless, MCU.
