Key result
Exercise-induced atrial extrasystoles predict AF in patients with LVH.
Why the study?
Prediction of atrial fibrillation is usually based on anatomical and functional atrial substrate characterisation, while the role of exercise-induced atrial extrasystoles as triggers is often neglected in patients with left ventricular hypertrophy.
Do exercise-induced atrial extrasystoles predict atrial fibrillation in patients with left ventricular hypertrophy?
Do exercise-induced atrial extrasystoles predict atrial fibrillation in patients with left ventricular hypertrophy?
Exercise-induced atrial extrasystoles may serve as a predictor for atrial fibrillation in patients with left ventricular hypertrophy.
Post-exercise atrial extrasystoles were associated with incident AF in LVH; leaves open incremental predictive value beyond substrate markers in prospective cohorts.
Prediction of atrial fibrillation (AF) is usually based on anatomical and functional characterisation of the atrial substrate, such as left atrial diameter, ejection fraction, and P wave duration. 1In this respect, triggers such as atrial extrasystoles are often neglected. 2Atrial extrasystoles may occur during or shortly after exercise as a result of acute atrial stretch, especially in patients with left ventricular hypertrophy (LVH) and diastolic dysfunction.As LVH may induce the atrial substrate and atrial extrasystoles are the trigger for AF, we reasoned that these exercise induced atrial extrasystoles may predict AF in patients with LVH.

Richard Folkeringa (2006) studied Left ventricular hypertrophy. Exercise-induced atrial extrasystoles was evaluated on Atrial fibrillation. Exercise-induced atrial extrasystoles were hypothesized to predict atrial fibrillation in patients with left ventricular hypertrophy.
