Abstract

Ten morphological variables describing electrocardiographic ventricular repolarization were considered, an addition to the conventional QT interval, in order to have a more complete description of the phenomenon. The computer program QTNEW was developed in order to analyze the repolarization segment automatically and to measure the variables. A final list of seven variables was obtained after the application of dimensionality-reduction techniques and did not include the QT interval. Six variables were independent of the QT, six were heart-rate independent, and all were age and body surface-area independent
