Induction of ventricular fibrillation in rabbit heart during fast pacing at 17°C. On the ventricular bipolar electrogram at the top, a recording of ventricular stimulation with progressively shortening pacing interval are presented. Red frames indicate the mapped space. V1 and V2 are mapped VF waves. The gradual shortening of the pacing interval from 2,000 ms to 470 ms (top maps) leads to increasing the conduction anisotropy because of the depression of conduction velocity along the transverse direction. Representative traces of optical transmembrane action potentials recorded from right (●) and left (*) ventricle areas are presented near activation maps.
