А. Representative isochrone AT maps during electrical pacing across the
normal-(border)-ischemic zones at the low and high levels of [К+].
Electrical step symbols indicate a site of pacing.
B. Representative maps of CV distribution in the normal (site of pacing)
and ischemic zones. The border zone was determined as an area with
transitional values of CV. The red numbers refer to ischemic area zone,
the blue -border zone, the black - normal area.
C. The representative profiles of CV on the ischemia-to-normal axes
indicated by dotted arrows in the corresponding epicardial maps of CV
(panel B). Note the higher CV at low [К+] as compared to high
[К+].
