A Study on the Applicability of Non-Linear Analysis of P-wave Duration Over Time to Predict Atrial Fibrillation Onset
نویسندگان
چکیده
Analysis of P-wave duration from the ECG has been widely used to predict the onset of atrial fibrillation (AF). Given the low amplitude of Pwaves, this index has been mainly computed by using signal-averaging algorithms, thus discarding the clinically relevant information from its time course. This work presents an alternative based on a nonlinear approach, the central tendency measure, to quantify the P-wave duration evolution over time.

Assessment of P-wave indices as atrial fibrillation predictors in psoriasis patients
Background: Psoriasis is a prevalent chronic T cell mediated inflammatory skin disorder. Recent studies have reported an increase in the incidence of arrhythmia in psoriasis patients who run an excessive risk of metabolic syndrome and cardiovascular diseases. P-wave dispersion (PWD) and duration are important electrocardiographic (ECG) markers employed to anticipate the risk of atrial arrhythmi...

Background: P wave dispersion (PWD) is defined as the difference between the maximum P wave duration (Pmax) and the minimum P wave duration (Pmin) in 12-leads of the surface electrocardiography. The aim of this study was to evaluate the values of PWD during atrial fibrillation (AF) after acute myocardial infarction (AMI). Methods: We prospectively evaluated atrial rhythms of 350 patients (251 m...

Abstract Background Prolonged P-wave duration and P-wave dispersion indicate interatrial conduction disturbance and early predict arrhythmia especially atrial fibrillation. Iron deposition in the atrial tissue might prolonged the atrial conduction time, and this study evaluated the P-wave prolongation and increased P-Wave dispersion in these patients. Materials and Methods Fifty patients w...

Introduction: Atrial fibrillation (AF) is the most common complication of cardiac surgery which may cause remarkable morbidity and complications. Identifying predicting factors of this arrhythmia can help prophylactic therapy. The present study is designed to investigate the hypothesis that HsCRP level and P-wave characteristics are associated with the incidence of post-operative AF. Methods: ...
