Example e34:
Solving for Potentials from an Activation Map
Creates potentials from an activation map fitted from example e33.
The activation sequence from 0 to 50 ms is used to construct potentials
on the torso surface with the use of a double layer transfer matrix.
The images below show front and back view of the torso and
the displaced epicardial and ventricular surfaces. The
black line on the heart shows the location of the wavefront.
The activation sequence on the heart and ventricles (0-50ms)
are shown with the resulting potential field on the torso surface.
The left image is a snapshot at 10 ms and the right image at
35 ms.
