Abstract
An example system and method of determining a likely core of a rotational source associated with a heart rhythm disorder are disclosed. A plurality of relative diffusion shapes associated with wave fronts is calculated at a plurality of time points associated with the rotational source. The wave fronts associated with heart signals. A plurality of intersecting points of a smallest relative diffusion shape and other relative diffusion shapes is determined. A bounded polygon of the intersecting points is defined as the likely core.
