Difference Between the First Medtronic Interrogation Report and the New 2-Page Report
This article explains the practical difference between a full post-surgery Medtronic programmer interrogation report and a shorter CareLink-style remote transmission summary.

Main Difference
The new 2-page PDF is a much shorter remote-transmission style report, while the first report was a full post-surgery Medtronic programmer interrogation report.
The first report was a 15-page full interrogation after implant or surgery. It included detailed technical pages: implant record, stimulation thresholds, measured device data, ECG strips, sensing tests, threshold tests, Quick Look, session summary, histograms, Cardiac Compass, VT/VF counters, lead trends, and battery/lead measurements.
The new report is only 2 pages and contains:
- Quick Look II summary: battery, impedance, thresholds, pacing percentages, arrhythmia counters, and observations.
- Current EGM: a short rhythm/electrogram strip from the remote interrogation.
Important Numerical Differences
| Item | First full report | New 5/17/26 report | Meaning |
|---|---|---|---|
| Date | 4/21–4/22/26, immediately after implant | 5/17/26 | The new report is a later follow-up. |
| Battery longevity | “Initializing” or not fully established yet | 10.2 years | The device now has enough information to estimate battery longevity. |
| Atrial impedance | Approximately 494 ohms | 513 ohms | Similar and apparently stable range. |
| RV impedance | Approximately 513 ohms | 494 ohms | Similar and apparently stable range. |
| Atrial capture threshold | Approximately 0.75 V @ 0.4 ms | 0.375 V @ 0.4 ms | Lower atrial threshold, which generally means less energy is needed to capture the atrium. |
| RV capture threshold | Approximately 0.75 V @ 0.4 ms | 0.875 V @ 0.4 ms | Slightly higher than before, but still close to the prior value. |
| Atrial sensed P wave | Around 4.3–4.6 mV | 3.4 mV | Slightly lower, but atrial sensing is still present in the summary. |
| Arrhythmia observations | No major events shown in the reviewed pages | No observations based on current interrogation | No flagged observations are shown in the 2-page summary. |
| Pacing | Early post-implant data | AP 92.2%, VP 0.0% | Mostly atrial pacing; no ventricular pacing shown for the summarized period. |
Most Clinically Relevant Difference
The new report shows VP 0.0%, meaning the device is apparently not pacing the ventricle during the period summarized, while atrial pacing is high at AP 92.2%.
That is not automatically bad. It may reflect the programmed mode, your own natural AV conduction, and the clinical strategy chosen by your electrophysiologist. However, it is exactly the kind of point the electrophysiology team should explain in context.
Why the New Report Is Shorter
The new report appears to be a CareLink remote transmission report, not the full in-office programmer printout. It provides Cleveland Clinic with the key values but does not include all the detailed diagnostic pages found in the full interrogation.
In practical terms, the shorter report is a summary. The longer report is a more complete technical printout.
Suggested Question to Cleveland Clinic
You could write:
Bottom Line
The new report does not necessarily mean that less information was collected. It likely means that Cleveland Clinic sent you only the short remote summary rather than the complete technical Medtronic interrogation packet.
The key reassuring elements visible in the 2-page report are that battery longevity is estimated at 10.2 years, lead impedances appear in a similar range to the first report, no observations are listed, and the summary shows no ventricular pacing during the period reviewed.
