Abstract :
During cardiac surgery, atrial fibrillation was induced by rapid pacing. The excitation of the free wall of the right and left atrium was recorded by a multiple recording electrode (240 leads) covering an area of 20 cm2. The spread of activation was visualized by reconstructing series of consecutive activation maps based on measurements of individual local activation times. The results demonstrate that atrial fibrillation in man is based on multiple wavefronts whose course is governed by temporal and spatial inhomogeneities in recovery of excitability
