Reentrant activity induced by Isoproterenol. Panel A: OAPs from the CN region (CN-His), fast and slow conduction pathways regions (FP and SP), and TC region near the CS recorded from sites 1–4 as indicated on the activation maps in panel B during spontaneous reentrant activity in the AVJ. The black dotted arrows show the propagation of reentrant activity Panel B: Activation maps showing the complex reentrant circuits during reentrant activity. The white arrows show the directions of conduction.
