Analysis of speed, curvature, planarity and frequency characteristics of heart vector movement to evaluate the electrophysiological substrate associated with ventricular tachycardia
Novel method to study ventricular conduction on surface ECG is presented. Speed, curvature, orbital frequency, planarity of filtered VCG loops was measured. Electrophysiology of post-infarct ventricular tachycardia was characterized.
