What does this research mean for the field?

Maximal exercise testing in children with physiologic pacemakers identifies functional abnormalities not apparent at rest, such as decreased atrial sensing and myopotential inhibition, and indicates that higher upper rate limits may be optimal for this population. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

The study aims to assess exercise testing as a method to identify pacemaker function abnormalities in children that may not be visible at rest.

Why the study?

Does maximal exercise testing identify abnormalities of pacemaker function not apparent at rest in children with physiologic pacemakers?

Key Points

The study aims to assess exercise testing as a method to identify pacemaker function abnormalities in children that may not be visible at rest.
Maximal exercise tests conducted on 24 children aged 4.5 to 18 years with physiological pacemakers.
Abnormalities were evaluated by monitoring lower and upper rate limits during exercise testing.
Sensing functions of atrial and ventricular captures were analyzed during exercise.
19 of 24 cases exhibited lower rate limits that correlated with programmed settings.
10 of 24 cases showed upper rate limits lower than programmed, with 6 children reaching the maximum limits.
Problems included decreased atrial sensing and myopotential inhibition in some patients, with further testing showing improvements.

Structured PICO

Does maximal exercise testing identify abnormalities of pacemaker function not apparent at rest in children with physiologic pacemakers?

Population

24 children (15 boys, 9 girls) from 4.5 to 18 years of age (median = 15) with implanted atrial synchronous physiologic pacemakers

Intervention

Maximal exercise testing

Outcome

Identification of abnormalities of pacemaker function and confirmation of set parameters not apparent at restsurrogate

Maximal exercise testing is valuable for identifying pacemaker function abnormalities, such as decreased atrial sensing and myopotential inhibition, in children with physiologic pacemakers.

Implication

May detect exercise-induced pacemaker issues missed at rest in children; hypothesis-generating, larger studies needed before routine adoption.
