Abstract

This paper presents a modeling procedure to measuring abnormal intra-QRS signals in the high resolution electrocardiogram (HRECG). Abnormal intra-QRS potentials (AIQP) are defined as very low-level notches and slurs in the high resolution QRS complex. AIQP are isolated using (i) parametric linear and (ii) non-linear modeling techniques for representing the predictable, smooth normal, part of the QRS from the original waveform. The first approach considers HRECG signals as time domain phenomena, although using the frequency domain for computational convenience. A discrete cosine
