Brief Summary:
This study is designed to show that a new lead, which paces the left bottom chamber (left ventricle) of the heart, is safe. Using a lead on the left side of the heart has been shown to potentially improve heart failure symptoms. The shape and size of this new lead may make it a good choice for patients or physicians.

Condition or disease Intervention/treatment Phase
Heart Failure Device: Pacing Lead (Model 4296 LV Lead) Phase 2

Detailed Description:
This study is a prospective, multi-center, non-randomized design trial. All consented patients who meet all inclusion and no exclusion criteria may receive the investigational lead. The study design has statistical power to show safety at one-month after implant.
