Fractional generalization of entropy improves the characterization of rotors in simulated atrial fibrillation

作者：

Highlights：

• A novel generalization of entropy based on complex order derivative operators.

• Generalized entropy is more sensitive to rotor dynamics than Shannon entropy.

• Optimization of entropy parameters yields a better characterization of reentries.

• Sustained rotors during fibrillatory propagation correlate with high entropy values.
