Regularization Techniques for ECG Imaging during Atrial Fibrillation: A Computational Study
The inverse problem of electrocardiography is usually analyzed during stationary rhythms. However, the performance of the regularization methods under fibrillatory conditions has not been fully studied. In this work, we assessed different regularization techniques during atrial fibrillation (AF) for estimating four target parameters, namely, epicardial potentials, dominant frequency (DF), phase...
متن کاملسنجش استعداد ابتلا به فیبریلاسیون دهلیزی با استفاده از تحلیلهای غیر خطی سیگنال الکتروکاردیوگرام
Atrial Fibrillation is a supra ventricular tachyarrhythmia, which is characterized by the deterioration of atrial mechanical function and aberrant. It has become a social and economic problem because a large percentage of the world population suffering from this disease. The early diagnosis of this fatal cardiac Arrhythmia can be prevented and managed it. In this study, we used non-invasive met...
متن کاملAssessment 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...
متن کاملClinical Significance of P Wave Dispersion in Prediction of Atrial Fibrillation in Patients with Acute Myocardial Infarction
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...
متن کاملA Simple Atrial Fibrillatory Wave Reconstruction Method for Frequency Analysis of Atrial Fibrillation Using Single- Lead Ecg
A cosine-function-based approximation method is proposed to reconstruct atrial fibrillatory wave in QRST intervals for estimating dominant frequency of atrial fibrillation (AF) using single-lead ECG. It is hypothesized that atrial fibrillatory waves in two adjacent QRST intervals can be approached by a cosine function and direct component. As harmonics of dominant frequency are neglected, the d...
