Table II.
ISI of the infarct, peri-infarct and normal zone.
| Group | Infarct zone (ISI, msec) | Peri-infarct zone (ISI, msec) | Normal zone (ISI, msec) |
|---|---|---|---|
| SO | 169.20±11.87 | 171.92±8.32 | 174.16±12.45 |
| MI | 142.11±5.09a | 149.98±8.35a | 151.15±7.74a |
| NRG-1 | 158.34±14.26b | 160.01±14.35b | 165.03±17.50b |
Data represent mean ± standard error of the mean of ISI of the infarct, peri-infarct and normal zone in SO, MI and NRG-1 groups, respectively.
a
P<0.05 vs. SO group
b
P<0.05 vs. MI group. SO, shame operation; MI, myocardium infarction; NRG-1, neuregulin-1; ISI, interspike interval.
