Integral Transform Technique for Monitoring Electrocardiograms.
Abstract
The paper applies time domain and filtered integral transform domain pattern recognition techniques to the problem of locating and discriminating between QRS-complexes and premature ventricular contractions in electrocardiograms. The data set consists of sixteen 100-second single lead electrocardiogram records. Sufficient electrocardiogram and pattern recognition theory is included to explain the technique and the results. Three different integral transforms are evaluated: the discrete Fourier, the Walsh, and an accidentally discovered transform similar to the Walsh. Ninety-seven percent of the QRS-complexes and premature ventricular contractions (PVC's) in the records evaluated were located correctly. The three transform techniques classified between 90.8% and 92.5% of the QRS-complexes correctly and 85.6% and 93.2% of the PVC's correctly. (Author)
