Computerized Baseline Estimation and Averaging of Exercise Electrocardiograms.

Abstract

A cubic spline estimator of baseline variation and concepts of state-space can be combined to remove the baseline variation often encountered in stress electrocardiography. Since only one node, or knot, per cardiac cycle (THE PR segment) is defined, baseline variation is removed with minimal effect on the low-frequency information within the cardiac cycle. The frequency response of the baseline estimator is a function of the heart rate. (Author)
