FREEDOM - A Frequent Optimization Study Using the QuickOpt Method

Abbott Medical Devices·interventional·Posted Jan 4, 2007·Updated Feb 19, 2019

In Brief

A clinical study evaluating Control and QuickOpt for Cardiac Arrhythmias and Heart Failure. Completed, enrolled 1,647 participants across 2 sites.

Detailed Summary

The objective of this study is to demonstrate that frequent atrio-ventricular (AV/PV) and inter-ventricular (V-V) delay optimization using QuickOpt in patients with cardiac resynchronization therapy device results in improved clinical response over standard of care (i.e. empiric programming or one-time optimization using any non-intracardiac electrogram optimization methods).
