  • 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 0.5 mg 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)
