Haemodynamic results
| Baseline dP/dtmax (mm Hg/s) | BIVP dP/dtmax (mm Hg/s) | ΔdP/dtmax (%) | P value | |
| All patients (n=27) | 777±180 | 899±205 | 16.3±13.8 | <0.001 |
| Acute CRT responders (n=18) | 775±157 | 949±169 | 23.3±10.6 | <0.001 |
| Acute CRT non-responders (n=9) | 781±230 | 799±241 | 1.9±5.3 | 0.30 |
Variables are presented as mean±SD.
BIVP, biventricular pacing; CRT, cardiac resynchronisation therapy; dP/dtmax, peak positive time derivate of left ventricular pressure rise.
