Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The increase of dP/dt during bi-ventricular stimulation is measured via an intracardiac pressure-wire. These measurements are performed during the procedure. | — |
Secondary
| Measure | Time frame |
|---|---|
| Cardiac output is determined under different V-V-intervals. For these measurements an intracardiac pressure-wire is used. | — |
