95% Atrial Pacing Does Not Mean Pacemaker Dependency

01About the publication

The atrial pacing percentage stored in a pacemaker report is not, by itself, a measure of pacemaker dependency. A high percentage shows that the device paced the atrium often. It does not prove that the heart would fail to sustain a tolerated rhythm without the pacemaker.

This publication, co-authored by Prof. Dr. Hakan Uçar, is an images-in-electrophysiology case report in the Journal of Interventional Cardiac Electrophysiology. Its title states that 95% atrial pacing does not mean pacemaker dependency.

02What question does the title raise?

Pacemaker dependency means that loss of pacing would be expected to cause hemodynamically intolerable bradycardia or asystole. The atrial pacing percentage is a counter on the device report. The two are not interchangeable.

The article’s title frames that distinction around a reported pacing burden of 95%.

03What the open record contains

PubMed has not indexed an abstract for this article. The case narrative, the tracings and the figure are in the publisher’s full text.

The publicly available publisher record supports the following frame:

• The article type is an images-in-electrophysiology case report.
• The contribution statement refers to management of the patient in the singular.
• The funding note states that no external funding was received for the case report.
• The data note states that no datasets were generated or analysed.
• The authors declare no competing interests.

This page does not reconstruct case details that are not in the open record.

04Study limitations

These limits follow from the article type and from what is openly indexed.

• A case report does not represent the outcomes of a patient cohort.
• A single observation does not set a general rule for reading pacemaker counters.
• The clinical course and figure are in the journal article; PubMed has no abstract.
