AF and micro-AF screening study

A Norwegian screening study is exploring the occurence of AF and micro-AF in intermittent 30s thumb-ECGs recorded using the Zenicor device.

The ECG recordings in the study are processed by the Zenicor medical system that uses the Cardiolund ECG Parser for automated analysis.

The study shows that two-week intermittent ECG screening identified few cases of new-onset AF but a substantial number of patients with “micro-AF.” The occurence of “micro-AF” was associated with an increased risk of major cardiovascular events, albeit with an intermediate risk compared to those with new-onset AF.

The study is reported in the publication: Screen-Detected Atrial Fibrillation and “Micro-Atrial Fibrillation” and Risk of Cardiovascular Events after Myocardial Infarction in Elderly Patients by Berge T, Myhre P.L., Kalstad A.A.,Laake K., Tveit S.H., Onarheim S., Solheim S., Seljeflot I., Arnesen H., Tveit A. in Cardiology 2023;148:72–77.
