Differences on the correlation dimension of MIT-BIH ECG database recordings

The author investigates the differences in the correlation dimension (D/sub 2/) measured from electrocardiograms (ECG) of normal and sick subjects obtained from the MIT-BIH Arrhythmia Database. It is observed that there is a greater variability in the dynamics of the system underlying the ECGs recorded from pathological subjects than from normals. A particular attention to make results repeatable is paid.<
