Study investigating prognostic implications of supraventricular arrhythmias

A recent study has investigated the prevalence and prognostic implication of progressive supraventricular arrhythmias from frequent supraventricular ectopic complexes, isolated, in bi- or trigeminy, to supraventricular tachycardias with different characteristics.

In this study, the database with ECG-recordings from the STROKESTOP I study were re-evaluated using the Cardiolund ECG Parser. The results of the automated ECG analysis where filtered to detect individuals with frequent supraventricular ectopic complexes or runs. Detected episodes were manually re-examined to confirm the findings.

The study results shows that individuals with the most AF-similar supraventricular tachycardias, irregular and lacking p-waves (termed micro-AF) had the highest risk of developing AF (hazard ratio 4.3).
