The role of single‑lead ECG in screening for atrial fibrillation deserves more attention

We read with great interest the article titled “Screening for paroxysmal atrial fibrillation in primary care using Holter monitoring and intermittent, ambulatory single-lead electrocardiography ” by Karregat's team [ [1] Evert S. Karregata P.M. Gurpb Nicole Verbiest-van Bouwmana Anne C. Uittenbogaarta H.E.J.H.S.B. Himmelreicha Jelle C.L. Lucassena Wim A.M. Krulc Sebastien P.J. van Kesterend Henri A.M.

The study by Karregat et al. indicates that the diagnostic accuracy of MyDiagnostick—a single-lead ECG device is limited.
