* New non-invasive technologies, such as patches, smartwatches, and smartphone ECGs, are also being evaluated for their effectiveness in detecting arrhythmias.
* The review highlights that while these newer methods show high diagnostic yields, the best monitoring approach remains uncertain due to insufficient direct comparisons between the technologies.
The ESC guidelines recommend screening for arrhythmic events in patients with adult congenital heart disease (ACHD), but the best detection method is unclear.
A study compared two methods of monitoring arrhythmias in ACHD patients: implantable loop recorders (ILRs) and smartphone-based single-lead electrocardiograms, involving a total of 116 patients.
Findings showed that both methods had similar effectiveness in detecting arrhythmias, with smartphone monitoring being a viable, non-invasive alternative, particularly for patients without syncope.
