Ensure Cardiac Resynchronization Therapy Study

The purpose of this study is to gather information on how doctors program particular settings on cardiac resynchronization therapy implantable cardiac defibrillators (CRT-Ds), to analyze how these settings affect the amount of cardiac resynchronization therapy (CRT) patients receive and to evaluate the therapy approach for converting abnormally fast heartbeats into normal heartbeats. There are no experimental devices or procedures involved in this study.
