| RV ratio4-150 | 0.246 | 0.237 | NS |
| LV pre-ejection (ms) | 112 (18) | 97.8 (17.6) | < 0.001 |
| LV ejection time (ms) | 377 (61.4) | 307.6 (40.8) | < 0.001 |
| LV ratio4-150 | 0.229 | 0.317 | < 0.001 |

| VCF (cm/s) | 1.12 (0.33) | 1.3 (0.2) | < 0.05 |
Values are mean (SD).
↵4-150 Ratio of pre-ejection time to ejection time.
LV, left ventricular; RV, right ventricular; VCF, velocity of circumferential fibre shortening.
