A Clinical Evaluation of the Current™ Radio Frequency (RF) Implantable Cardioverter Defibrillator (ICD) Models 2215/1215 and Promote™ RF Cardiac Resynchronization Therapy Defibrillator (CRT-D) Model 3215 Pulse Generators
This study is a prospective, non-randomized, multi-center clinical trial that will assess the
safety and effectiveness of investigational models of the Promote™ RF CRT-D and Current™ RF
ICD devices. These new ICD and CRT-D devices have new features that allow the device to
periodically check how much energy is needed to pace a patient's heart and to automatically
adjust the amount of energy used to pace the heart.

ICD devices. These new ICD and CRT-D devices have new features that allow the device to
periodically check how much energy is needed to pace a patient's heart and to automatically
adjust the amount of energy used to pace the heart.
All patients enrolled in the study will have their device tested to determine if the device
can automatically measure how much energy is needed to pace the patient's heart. If the test
is successful, the patient's device will be programmed to turn that feature on. 3 months
after enrollment, the patient will return to the clinic to have their device re-tested using
an automatic test method to measure the amount of energy needed to make the patient's heart
beat. A manual test method will also be used to measure the amount of energy needed to make
the patient's heart beat. The intent of the study is to show the automatic method works just
as well as the manual method.

Inclusion Criteria:
- Have an approved indication, as outlined by American Heart Association/Heart Rhythm
Society (AHA/HRS) guidelines, for implantation of an ICD or CRT-D for the treatment of
life-threatening ventricular tachyarrhythmia(s) or heart failure, or undergo revision
of their ICD or CRT-D system to replace the pulse generator.
- Have the ability to provide informed consent for study participation and be willing
and able to comply with the prescribed follow-up tests and schedule of evaluations.
Exclusion Criteria:
- Have a classification of Status 1 for cardiac transplantation or consideration for
transplantation over the next 3 months.
- Have had a recent myocardial infarction, unstable angina or cardiac revascularization
(percutaneous transluminal coronary angioplasty (PTCA), Stent or Coronary Artery
Bypass Graft(CABG)) within 40 days of enrollment.
- Have had a recent cerebrovascular accident (CVA) or transient ischemic attack (TIA)
within 3 months of enrollment.
- Are allergic to dexamethasone sodium phosphate (DSP).
- Be currently participating in a clinical investigation that includes an active
treatment arm.
- Be pregnant or are planning for pregnancy within 6 months following enrollment.
- Have a life expectancy of less than 6 months.
- Be less than 18 years of age.
