Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects who have a Class I or II indication for implantation of a single chamber ventricular pacemaker according to ACC/AHA/HRS 2008 guidelines and China guideline.
  • Subjects who are willing to participate in study through consent and willing to undergo study specific required procedures with expectancy of geographically stable for follow up duration.
  • Subjects who are at least 18 years of age.

You may not qualify if:

  • Subject has an existing or prior pacemaker, ICD or CRT device implant.
  • Subject has unstable angina pectoris or has had an acute myocardial infarction (AMI) in the 30 days prior to eligibility assessment.
  • Subjects with current implantation of neurostimulator or any other chronically implanted device which uses current in the body. Note that a temporary pacing wire is allowed.
  • Subjects with a mechanical tricuspid valve, implanted vena cava filter, or left ventricular assist device (LVAD).
  • Subjects who are morbidly obese and physician believes telemetry communication of ≤5 inches (12.5 cm) could not be obtained with programmer head.
  • Subjects whose femoral venous anatomy is unable to accommodate a 23 French introducer sheath or implant on the right side of the heart (for example, due to obstructions or severe tortuosity) in the opinion of the implanter.
  • Subjects who are considered as unable to tolerate an urgent sternotomy.
  • Subjects with a known intolerance to Nickel-Titanium (Nitinol) Alloy.
  • Subjects for whom a single dose of 1.0mg dexamethasone acetate may be contraindicated.
  • Subjects with a life expectancy of less than 12-months.
  • Subjects who are currently enrolled or planning to participate in a potentially confounding drug or device trial during the course of this study. Co-enrollment in concurrent trials is only allowed when document pre-approval is obtained from the Medtronic study manager.
  • Pregnant women or breastfeeding women, or women of child bearing potential and who are not on a reliable form of birth regulation method or abstinence.
  • Subjects with medical condition which precludes patient from participation in the opinion of the Investigator.
