А. Representative epicardial maps of ATs and ARIs distribution in three
rats across ischemic, border and normal zones at the low and high levels
of [K+].
Numbers indicate the values of ATs and ARIs in individual leads. The
filling color in the maps corresponds to a time scale (red for short and
blue for long time values). The red, blue, and black numbers refer to
the ischemic area with ST–segment elevation and activation delay; the
border zone with ST–segment elevation without activation delay; and the
normal area without AT and ARI abnormalities, respectively.
B. The representative profiles of ATs and ARIs on the ischemia-to-normal
axes indicated by dotted arrows in the corresponding epicardial maps of
ATs and ARIs. Red, blue, and black sections of the diagrams correspond
to the ischemic zone, border zone, and normal zone, respectively. See
the absence of the border zone at [К+]=6.28 mM.
C. Representative electrograms recorded in the ischemic (1), border (2)
and normal (3) zones.
