P Wave Area for Quantitative Electrocardiographic Assessment of Left Atrial Remodeling

Abstract

BACKGROUND Left atrial (LA) dilation provides a substrate for mitral regurgitation (MR) and atrial arrhythmias. ECG can screen for LA dilation but standard approaches do not assess LA geometry as a continuum, as does non-invasive imaging. This study tested ECG-quantified P wave area as an index of LA geometry. METHODS AND RESULTS 342 patients with CAD… (More)
