Fig. 1: Waves of excitation following high frequency stimulation at the apex.


Fig. 2: Wave pattern (a single spiral) on the ventricular surface, during monomorphic tachycardia.


Fig. 3:Ventricular cross section showing reentrant activity (a scroll) during monomorphic tachycardia.


Fig. 4: View of the three dimensional structure of a single scroll wave.


Fig. 5: Scroll wave reentant pattern on the surface of the ventricles, and on cut-away section.


Fig. 6: Transparent view of scroll wave.


The following are extra unpublished figures:


Normal propagation following a single stimulus applied at the apex of the ventricles.


Another view of normal waves. Here the stimulus was applied to the endocardial wall of the left ventricle.
