Key result
Transtelephonic pacemaker monitoring demonstrated high diagnostic accuracy compared to physical examinations, with a sensitivity of 94.6%, specificity of 98.5%, PPV of 93.3%, and NPV of 98.8%.
Why the study?

Does transtelephonic pacemaker monitoring accurately assess pacemaker function compared to physical examination in patients with pacemakers?
Transtelephonic pacemaker monitoring demonstrates high diagnostic accuracy and clinical utility for identifying pacemaker malfunctions and arrhythmias compared to in-person clinic visits.
Answers are grounded in this paper and cite their sources.
May support remote pacemaker monitoring to reduce visits; leaves open randomized trials before practice change.
The diagnostic accuracy of transtelephonic pacemaker monitoring (TTM) has been quantified in a retrospective study involving 369 patients in three U.S. cardiac centers. Using existing medical records, TTM findings in a total of 413 reports were judged for equivalence to the findings of subsequent physical examinations in pacemaker clinics. This study found TTM follow-up testing to have a sensitivity of 94.6%, specificity of 98.5%, positive predictive value of 93.3%, and negative predictive value of 98.8%. The study also documents the clinical utility of TTM in identifying various modes of pacemaker malfunctions and instances of significant arrhythmia.

Gessman et al. (1995) conducted an observational in Pacemaker follow-up (n=369). Transtelephonic pacemaker monitoring (TTM) vs. Physical examinations in pacemaker clinics was evaluated on Diagnostic accuracy (equivalence to findings of subsequent physical examinations) (Sensitivity 94.6%, specificity 98.5%, PPV 93.3%, NPV 98.8%). Transtelephonic pacemaker monitoring demonstrated high diagnostic accuracy compared to physical examinations, with a sensitivity of 94.6%, specificity of 98.5%, PPV of 93.3%, and NPV of 98.8%.
