Design and implementation of telecardiology

Abstract

This project gives specifications in the design and implementation of a low cost wearable ECG system. A detailed explanation of the various modules of the design and their implementations is provided. Each module was successfully simulated and then implemented. The system design aims to provide solutions to the problems encountered in acquiring signal from the body, as well as providing remote transmission, of ECG data. A remote device is attached to the person being monitored. The remote device acquires the raw ECG data from the Leads which are placed in predefined areas of the body. The data is digitized through a PIC programmed as an ADC UART device. The data is transmitted wirelessly using a Bluetooth technology (Bluegiga device in our case) to an android enabled cell phone which loads the data through the GPRS technology to a website. The reconstruction of the sampled digitized ECG is performed at the website side. The access rights of the web site are with the hospital where the doctor can monitor the ECG of the patient at home. The complete design is dissected into various modules which are discussed individually.
