The electrical propagation of MI was obtained in different groups by electrical mapping and velocities of electric conduction was calculated.

(c) Representative epicardial activation maps located on the border between the noninfarcted myocardium and infarcted myocardium after 28 days’ treatment.

(d) Transverse conduction velocity and longitudinal conduction velocity were calculated based on epicardial activation maps.

(e) Schematic diagram of PES.

(f) Electrograms of induced arrhythmias recorded after 28 days’ treatment after PES.
