Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to characterize left ventricular acute hemodynamic and electrical responses during cardiac resynchronization therapy (CRT) with different Multipoint Pacing (MPP) settings, and assess the relationship between electrical activation patterns and hemodynamic measurements during these pacing settings.
