An automatic baseline drift correction method

Baseline drift correction is a necessary step before measuring the amplitudes and durations of the cardiac waves in automated ECG (electrocardiographic) processing. A novel method for automatic baseline drift correction is described. This method uses many reference points per cardiac cycle which are precisely determined by means of a rigorous mathematical method instead of one reference point empirically determined, utilized by other methods. It can handle 'jumps' since it considers each cardiac cycle separately, whereas the other methods consider all cardiac cycles simultaneously. Extensive experimentation using the CSE-ECG library indicates that this method gives better results than the other methods.<
