One way analysis of variance: summary of QRS duration (ms)
| Ventricular arrhythmias | Mean (SD) | F | Prob > F |
|---|---|---|---|
| None | 137.77 (26.21) | 1.78 | 0.16 |
| Minor | 145.12 (24.26) | ||
| nsVT | 138.28 (26.71) | ||
| sVT or VF | 163.5 (14.55)5-150 | ||
| Total | 144.03 (25.09) |
↵5-150 p for the difference with no arrhythmias = 0.18.
VF, ventricular fibrillation; nsVT, non-sustained ventricular tachycardia; Prob, probability; sVT, sustained ventricular tachycardia.
