Pacemaker FAQ

From Computing and Software Wiki

This page contains answers to the Frequently Asked Questions about the Pacemaker.

Requirements

1. Section 2.5.2 – Implant Phase
   7. Testing the system sensing and pacing efficacy.
   • What kind of test is made?
   • Which of these parameters are evaluated?
     A: See #6 in the section above 2.5.2
2. Part 5.2 said URI is the min time between a ventricular event and the next ventricular pace. Then why is URI effective in modes without ventricular pacing nor sensing, such as AAT, AOO (Table 6, page 28)?
   A: “URI” should be “URL interval” in the question. For AAT, trigger paces must not be faster than URL. AOO is constant rate pacing at LRL. So long as LRL < URL (one of many implicit parameter constraints) AOO will pace slower than URL.
   The requirement could have been broadened to atrial-only modes. Alternatively, strict reading that URL does not apply to atrial-only modes is acceptable as well.
