P Wave Area for Quantitative Electrocardiographic Assessment of Left Atrial Remodeling
Figure 5
Atrial Fibrillation/Flutter Risk as Stratified by LA Remodeling Indices.
Kaplan-Meier plots relating baseline P wave area (5A) and body surface area indexed LA area (5B) to follow-up risk for AF/AFl. Note that both ECG and CMR indices demonstrated increased risk for AF/AFl among patients in the highest quartile of LA remodeling.
