Summary of median (interquartile range) V-CoS scores and heart rate at each stage of recovery post-exertion
| Non-SCD (n = 32) | SCD (n = 28) | P-value* | |
|---|---|---|---|
| V-CoS scores | |||
| Peak exertion | 97.3% (94.9–99.1%) | 92.8% (89.8–96.3%) | P < 0.05 |
| Recovery 2 min | 98.9% (96.9–99.5%) | 95.2% (91.1–97.2%) | P < 0.01 |
| Recovery 5 min | 99.5% (97.8–99.8%) | 98.4% (95.8–99.3%) | P = NS |
| Recovery 10 min | 99.8% (99.1–100%) | 99.8% (98.7–100%) | P = NS |
| Heart rate | |||
| Peak exertion | 137 (120–153) | 138 (129–155) | P = NS |
| Recovery 2 min | 94 (88–108) | 101 (90–112) | P = NS |
| Recovery 5 min | 90 (80–99) | 91 (84–96) | P = NS |
| Recovery 10 min | 88 (78–95) | 87 (83–98) | P = NS |
NS, not significant; SCD, sudden cardiac death; V-CoS, ventricular conduction stability.
