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
