摘要
Disclosed herein are techniques for graphically indicating aspects of rotors (such as pivot points of rotors) associated with atrial or ventricular fibrillation. Embodiments can include receiving, using a processor, an electrogram for each of a plurality of spatial locations in a heart, each electrogram comprising time series data including a plurality of electrical potential readings over time. Embodiments can also include generating, from the time series data, an entropy dataset including a plurality of Shannon entropy values corresponding to the plurality of spatial locations in the heart. Also, examples can include generating, from the entropy dataset, an entropy map including a plurality of graphical indications of the Shannon entropy values at the plurality of spatial locations in the heart, wherein the entropy map can include an image of the heart and graphical indications of locations of aspects of rotors in the heart (such as pivot point of rotors).
