| Abstract: | We have studied the dynamics of reentry inside the sinoatrial node (SAN). We have found that reentry is unstable at high intercellular conductance. Rotating reentry induces a slow migrating crescent-shaped functional block near the SAN boundary. Abnormal conduction from atrial tissue into the SAN occurs after decay of the reentry. Acetylcholine increases the lifespan of reentry in the SAN. |
