Design & Implementation of Portable Electrocardiogram System using MSP430

Since an embedded circuit board is lower in cost, smaller in size, and lower in power consumption than a PC. Removal of baseline wanders and power line interference in ECG signal is a classical problem. A new method is proposed to remove baseline wander and power line interference in ECG signal based on notch filter design. According to the waveform distortion problem existed in the portable electrocardiogram (ECG) monitoring system and working principle used in portable ECG monitoring system, the paper proposes an overall design idea of portable ECG monitoring system based on MSP430 and implementation of system hardware and software. The paper also shows simulated results of removal of the base line interference and High frequency noise signal from the original ECG Signal. This developed work (Hardware & Software) is of low cost with regards to traditional Medical Monitoring equipment appears as a great alternative to be used in the medium and low complexity medical assistance services. This system can realize the effective real-time diagnosis and monitoring. This system can be applied widely.
