Figure 2 The insertion site of a large pectinate muscle to the underlying atrial tissue, serving as an anchoring site for re-entrant wave fronts (data from tissue no. 10). During ACh infusion (1 µmol/l), a single and stationary re-entry was induced. The pathway of the tip of the re-entrant wave front circled in a clockwise direction (A to E) around the insertion site of a large pectinate muscle to the underlying atrial tissue (see Fig. 1B). (F) The location of channels (Chn) around the insertion site. (G) The actual electrograms registered by these channels during stationary re-entry. During re-entry, the pseudo-ECG recording reveals regular tachycardia (H).
