The results might be interpreted in two ways: 1) left atrial abnormality is a marker of undiagnosed atrial fibrillation, and the true stroke "risk" is mediated through atrial fibrillation; and 2) an atrial abnormality itself may increase risk of thrombus formation and thus stroke. Alexander B, Tse G, Martinez-Selles M, Baranchuk A. Curr Cardiol Rev. EKG said sinus tachycardia, left atrial enlargement, borderline report.
