Abstract WMP64: Utility of Left Atrial Abnormality on Admission Electrocardiography in Acute Ischemic Stroke

Introduction and Hypothesis: Clinical categorization of ischemic stroke is very important to select the antithrombotic therapy for preventing the recurrent stokes. However, about 25% of ischemic stroke is the stroke for undetermined cause, termed as cryptogenic stroke. Recently, proactive detecting of paroxysmal atrial fibrillation (PAF) in cryptogenic stroke has gained attention. P-wave terminal force in lead V1 (PTFV1) of electrocardiography (ECG) is a specific indicator of left atrial abnormality. In this study, we tested PTFV1 for the utility of PAF detection and further clinical categorization in acute ischemic stroke. Methods: One hundred forty eight consecutive acute ischemic stroke patients were admitted to our hospital from September 2014 to March 2016. We included 105 patients (mean age 72.8±13.4 years), who had sinus rhythm on admission 12-lead ECG without atrial fibrillation, or cardiac pacing. PTFV1 (mmхsec) of participants was assessed, and had analyzed the association with PAF detection in ...
