P wave analysis in 2464 orthogonal electrocardiograms from normal subjects and patients with atrial overload.
SUMMARY The purpose of this study was to establish limits of normal for P wave measurements, and to propose criteria for routine electrocardiographic readings and for multivariate analysis to recognize left atrial overload (LAO) and right atrial overload (RAO) in the orthogonal electrocar-diogram (ECG). Frank ECG's were obtained from 2464 subjects, including 580 normals, 164 patients with mitra...
متن کاملThe signal-averaged electrocardiogram of P wave in patients with documented atrial fibrillation or flutter and in patients with left or right atrial overload without atrial fibrillation.
To evaluate the significance of the signal-averaged P wave in various pathological conditions of the atrium, signal-averaged electrocardiograms and echocardiograms were studied in the following 4 groups: (1) 10 normal subjects (control group), (2) 24 patients with paroxysmal atrial fibrillation or flutter (AF) (AF group), (3) 12 patients with left atrial overload without AF (LA group), and (4) ...
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...

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...
