Background and Purpose-Atrial cardiomyopathy is associated with an increased risk of ischemic stroke. P-wave terminal force in lead V 1 , P-wave duration, and maximum P-wave area are electrocardiographic parameters that have been used to assess left atrial abnormalities related to developing atrial fibrillation. The aim of this systematic review and metaanalysis was to examine their values for predicting ischemic stroke risk. Methods-PubMed and EMBASE databases were searched until December 2016 for studies that evaluated the association between P-wave indices and stroke risk. Both fixed-and random-effects models were used to calculate the overall effect estimates. Results-Ten studies examining P-wave terminal force in lead V 1 , P-wave duration, and maximum P-wave area were included. P-wave terminal force in lead V 1 was found to be an independent predictor of stroke as both a continuous Key Words: atrial fibrillation ◼ electrocardiography ◼ heart atria ◼ odds ratio ◼ stroke P-Wave Indices and Risk of Ischemic Stroke
