Spontaneous activation under atrial fibrosis: A model using complex order derivatives

•An atrial fibrosis model using complex order derivatives in the space variable.•Fractional model conditions yielding unstable solutions.•Fractional order modulates the generation of spontaneous electrical activity. The computational modeling of the cardiac electrophysiology allows assertive and qua...
