To determine the normal values of P wave duration and P dispersion (Pd=maximum P wave duration-minimum P wave duration) in healthy children, electrocardiograms of 232 healthy children (143 boys, 89 girls, aged 7 to 15 years) were examined. There was no significant gender difference in maximum P wave duration (103+/-9.5 msec vs 102+/-8.4 msec, p=0.23) or P dispersion (27.2+/-5.3 msec vs 26.8+/-6...

BACKGROUND P wave dispersion is an independent predictor of atrial fibrillation. P wave dispersion is associated with inhomogeneous and discontinuous propagation of sinus impulses. The purpose of this study was to investigate P wave dispersion and transthoracic echocardiographic findings in elite women basketball players. METHODS We recruited 27 well-trained woman athletes with a training his...

INTRODUCTION Hypertension and obesity in adults have been linked to increased EKG P-wave dispersion; the association has been shown in relation to hypertension, left ventricular hypertrophy and atrial enlargement. Though studies in children have linked P-wave dispersion to left ventricular hypertrophy, scant pediatric literature relates P-wave dispersion to hypertension and obesity. OBJECTIVE...

Objective: The aim of the study was to investigate the impact of P-maximum and P-wave dispersion on the long term clinical outcome after successful percutaneous balloon mitral valvuloplasty (PBMV) in patients with mitral stenosis (MS) and sinus rhythm. Also to test the correlation between P-variables and right ventricular function and pulmonary artery pressure before and after PMBV. Methods: Ei...
