Brief summary: The primary objective of this clinical investigation is to evaluate the safety and effectiveness of the EASYTRAK 4 STEERABLE LV lead.

Detailed description: This is a prospective, multi-center clinical study is to evaluate the safety and effectiveness of the EASYTRAK 4 STEERABLE LV lead.

Eligibility criteria: Inclusion Criteria:

* Must receive a commercially available Guidant CRT-P or CRT-D device
* Creatinine \< 2.5 mg/dL obtained no more than two weeks prior to enrollment
* Age 18 or above, or of legal age to give informed consent specific to state and national law
* Willing and capable of providing informed consent, undergoing a device implant, participating in all testing associated with this clinical investigation at an approved clinical investigation center and at the intervals defined by this protocol
* Geographically stable residents who are available for follow-up

Exclusion Criteria:

* Have a known hypersensitivity to a 1.0 mg (0.5 mg per electrode) nominal dose of dexamethasone acetate
* Have or had previous cardiac resynchronization therapy, a coronary venous pace/sense lead or attempted LV lead placement
* Have pre-existing cardioversion/defibrillation leads or right ventricular pacing leads other than those specified in the investigational plan (unless the investigator intends to replace them with permitted cardioversion/defibrillation leads)
* Currently requiring dialysis
* Have had a myocardial infarct, unstable angina, percutaneous coronary intervention, or coronary artery bypass graft during the preceding 30 days prior to enrollment
* Have hypertrophic obstructive cardiomyopathy or infiltrative cardiomyopathy (e.g., amyloidosis, sarcoidosis)
* Documented life expectancy of less than six months or expected to undergo heart transplant within the next six months
* Enrolled or participating in any concurrent study, including drug investigations, without Guidant written approval, that may confound the results of this study
* Have a pre-existing unipolar pacemaker that will not be explanted/abandoned
* Have a mechanical tricuspid heart valve
* Women who are pregnant or plan to become pregnant Note: Women of childbearing potential must have a negative pregnancy test within seven days of enrollment.
