This page contains answers to the Frequently Asked Questions about the Pacemaker.
Requirements
- 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
- 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. - 2.5.3 - Predischarge Follow-up (Page 12)
2. Reprogramming to final pre-discharge value- Is there any special values for parameters?
A. No. This just means that the doctor can change parameters after implant, but before the patient leaves the hospital.
- Is there any special values for parameters?
- 3.6.1 - Permanent State (Page 17)
The normal pacing parameters programmed shall be used in the permanent brady state.- Which are these normal pacing parameters?
A. The ones that are currently programmed.
- Which are these normal pacing parameters?
- 3.6.2 - Temporary Bradycardia Pacing
The temporary brady parameters programmed shall be used in the temporary brady state.- Which are these temporary brady parameters?
A. An identical set of parameters to the permanent parameters, but changes in temporary parameters do not affect permanent parameters.
- Which are these temporary brady parameters?
The temporary state shall be capable of being used to temporarily test various system parameters or provide patient diagnostic testing.
- Which parameters are tested?
A. Any or all parameters that the physician wishes to try temporarily. - What is the "patient diagnostic testing".
A. Testing impedance/amplitude/threshold.
- Which parameters are tested?
