LOW COST ECG MACHINE DESIGN USING 8-BIT MICROCONTROLLER

Computer Engineering electronics Engineering Civil Engineering

Electrocardiogram (ECG) is considered to be the backbone of cardiology. In this we have explored a suitable way of designing an ECG machine using 8-bit microcontroller and certain discrete components. Proposed system consists of AD624 as instrumentation amplifier to amplify the bio potential received from body using electrodes. This signal is then passed through analog filters to filter out unwanted signal like baseline wander, power line noises etc. Microcontroller is used to process data digitally to send towards LCD screen to display or data logging unit to provide storage of ECG for future usage. Finally we explored a way to transfer data over GSM Model to the physician. loading..
