Efficient QRS detection in wearable ECG devices for body sensor network

This paper presented an efficient QRS detection algorithm for wearable ECG devices used in body sensor network. The algorithm is based on interpolated finite impulse response filter and an approximated envelope to remove motion artifact in ECG signals captured from wearable devices. Evaluation of the performance was based on both MIT-BIH ECG database and ECG signals from wearable devices. It is shown that the proposed detector works well for both resting and exercise ECG signals.
