Brief summary
The purpose of this study is to evaluate noninvasive hemodynamics with MultiPoint™ Pacing (MPP) and biventricular (BiV) pacing under various vector combinations and paced delays in patients receiving cardiac resynchronization therapy (CRT).

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Systolic blood pressure changes in hemodynamics during BiV pacing and MPP | up to 6-months |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| echocardiographic changes to MPP programming guided by noninvasive hemodynamic measurements | 6 months | End systolic volume will be assessed at 6-month follow-up visit and compared to that of baseline. |
