Description
The conduction velocity of the electrical impulse during ventricular fibrillation is the ratio between the distance between two electrodes located in a direction perpendicular to the isochrones and the difference between their activation times (average of 5 determinations). Only maps in which both the input and output wavefronts are identified at the edges of the activation maps are used to determine the velocity. The wavelength of the activation process during VF is calculated as the product of velocity and refractoriness.
