| Incidence of triggered activity (%, n) | ||||
| PCL | 6 s | 1 s | 0.5 s | 0.25 s |
| NR | 60 (25) | 50 (14) | 40 (15) | 7 (14) |

Summary of the incidence, or fraction of myocytes, in which EADs or triggered activity were successfully induced by H2O2 in single patch‐clamped ventricular myocytes from NR vs. SHR hearts (n): number of myocytes. The statistical significance was assessed by a two‐tailed Fisher's exact test.
