Abstract:

A portable electrocardiogram(ECG) monitoring device is designed for people with arrhythmia, myocardial ischemia, premature beats, and other heart diseases, and it is used for disease detection and prevention. In this paper, the RT1025 front-end ECG signal acquisition chip is studied first, followed by the development of a denoising infinite impulse response filtering algorithm for common noise such as electromyogram noise and 50 Hz power frequency interference, and the completion of program design for ECG data acquisition and communication. This equipment is stable in working condition, simple in data acquisition and control, and serves as a model for the design of portable ECG acquisition equipment. It is also important for the prevention and real-time monitoring of cardiovascular diseases.

Key words: portable electrocardiogram, analog front end, infinite impulse response filtering algorithm, bluetooth communication
