Relation of Electrocardiographic Left Atrial Abnormalities to Risk of Stroke in Patients with Atrial Fibrillation

The P wave terminal force in lead V1 (PTFV1) on the 12-lead ECG quantifies left atrial (LA) structural and electrophysiological abnormalities. We aimed to evaluate the association between PTFV1 and cerebrovascular accident (CVA) as well as LA structure and function in patients with atrial fibrillation (AF). We conducted a cross-sectional study of 229 patients with AF (60 ±10 years, 72% male) with (n=21) and without (n=208) a history of CVA, who underwent pre-ablation ECG and cardiac magnetic resonance (CMR) in sinus rhythm.
