Incidence of spontaneous and pacing‐induced VT/VF
| Non‐sustained VT (≤30 s) | Sustained VT (>30 s) | VF | ||
|---|---|---|---|---|
| NR (n = 24 hearts) | Spontaneous | 13% (3/24) | 0% | 0% |
| Rapid pacing | 38% (9/24)* | 0% | 0% | |
| SHR (n = 30 hearts) | Spontaneous | 73% (22/30) | 27% (8/30) | 33% (10/30) |
| Rapid pacing | NA | NA | 66% (13/20)* |
Intact hearts were perfused with H2O2 to induce spontaneous VT/VF. *Rapid pacing to induce VF was attempted only on the hearts that had not manifested spontaneous VF. NA, not available.
