Sham group |
MI group |
CoPP-MI group |
CoPP + SnMP -MI group |
|---|---|---|---|---|
| n = 20 | n = 35 | n = 25 | n = 6 | |
| ÂQRS (cases >90°) |
59° ± 2 (0/20) |
128° ± 2**# (35/35) |
94° ± 5** (12/25) |
125° ± 7**# (6/6) |
| IQRS (mV) |
4.1 ± 0.2 |
2.6 ± 0.1**# |
3.6 ± 0.2 |
2.4 ± 0.2**# |
| TQRS (ms) | 14 ± 0.6 | 19 ± 0.5**# | 15 ± 0.5 | 18 ± 1.6**# |
Values are mean ± SEM; n, number of animals tested; ÂQRS, frontal QRS axis; IQRS, QRS amplitude index; TQRS, QRS duration; **p < 0.001 vs sham-operated; #p < 0.001 vs. CoPP-treated infarct.
