Global longitudinal strain corrected by RR-interval is a superior echocardiographic predictor of outcome in patients with atrial fibrillation

摘要

Background: Echocarcliographic assessment of systolic and diastolic function during atrial fibrillation (AF) is challenging. This study evaluates he prognostic value of strain in patients with AF and suggests a novel approach on how to Lake into account the varying heart cycle lengths in AF.
