Figure 3.21. Reentrant
APs from different size
rings. A. Ring sizes (from
top to bottom, in number
of cells): 600, 550, 500,
450, 350, 250, 150, 100, and
50, respectively. The CL for
reentry in each ring is
shown in parenthesis. All
reentries are sustained
except for the ring of 50
cells. B. Dependence of
reentrant APD on CL.
Changes in CL result
from changes in ring size.
The upper curve (solid
symbols) corresponds to
the maximum APD, and
the lower curve (open
symbols) to minimum
APD during the entire
course of alternating
reentrant propagation.
