The QT Interval as a Noninvasive Marker of Atrial Refractoriness.

Abstract

BACKGROUND Atrial refractoriness may be an important determinant of atrial fibrillation (AF) risk, but its measurement is not clinically accessible. Because the QT interval predicts incident AF and the atrium and ventricle share repolarizing ion currents, we investigated the association between an individual's QT interval and atrial effective refractory… (More)
