Abstract:
An algorithm for ECG inflexions detection was improved with higher precision, simpler and faster calculation by introduction of a digital filter. Firstly, dig ital filter should have no phase displacement, so that each inflexion would not change its position; Secondly, the slope was an average of the slopes of several points in order to improve the ability of tolerating noises by a right threshold value; thirdly, the character of each inflexion was different, so the algor ithm should be adjusted according to each inflexion.
