Number of Participants
Patients with heart failure that meet current indication for cardiac resynchronization therapy.
The purpose of this study is to test both the good and bad effects of using an investigational right atrium lead and CRT-D device during cardiac resynchronization therapy. The right atrium lead has a sensor that will automatically calculate the best time to pace the heart. The study will compare the responses to CRT-D therapy in patients receiving the automatic optimization in the device or by an echocardiogram.
All participants will receive an investigational right ventricular lead and device along with two approved leads. After implant, participants will be randomly assigned to have the device optimized automatically or by echocardiography. All participants will have routine device follow-up.
