Wireless ECG Using Bluetooth

Abstract

The Electrocardiogram (ECG) is an essential diagnostic tool that measure and record the electrical activity of the heart. A wide range of heart conditions can be detected when interpreting the recorded ECG signals. These qualities make the ECG a perfect instrument for patient monitoring and supervision. The commonly used ECG machine used for diagnosis and supervision at present is expensive and stationary. With the recent advance in technology, there are possibilities to create a small sized wireless ECG system capable of transmitting ECG signal via Bluetooth technology to a Laptop or PDA using LABVIEW at low cost and at low power dissipation powered by a cellular phone battery. In the present research work a small sized wireless ECG embedded system is developed to make the patient more mobile without losing the reliability of the ECG sensor. It consists of an amplifier, filtering, PIC microcontroller, Bluetooth Technology and LABVIEW as a platform for wireless transmission. With the use of a PIC microcontroller the analogue signal is digitally converted at a specific sample rate that based on the resolution of the ECG-signals. The digital data will be transmitted to Laptop on Bluetooth protocol where the digital signal can be processed in LABVIEW and graphically can be displayed.
