Comparing three methods of calculating temporal ECG patterns from body surface potential maps

The objective of this study was to compare three methods for reducing temporal data from multiple-lead electrocardiograms (ECG) based on applying the Karhunen Loeve (KL) expansion. ECGs from 117 unipolar thoracic leads were recorded simultaneously for 15 seconds during normal sinus rhythm from 204 patients with underlying heart disease. The data were signal… (More)
