P wave duration and P dispersion in healthy children.
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...
متن کاملEffects of haemodialysis on maximum P wave duration and P wave dispersion.
BACKGROUND Analysing a 12-lead surface electrocardiogram (ECG), the inter-lead variability of the P wave interval, i.e. P wave dispersion, is defined as the difference between the maximum and the minimum P wave duration. Our aim was to assess the effect of haemodialysis on P wave duration and dispersion in non-diabetic patients with end-stage renal failure on chronic haemodialysis. METHODS Tw...
متن کاملP Wave Dispersion and Maximum P Wave Duration Are Independently Associated with Rapid Renal Function Decline
The P wave parameters measured by 12-lead electrocardiogram (ECG) are commonly used as noninvasive tools to assess for left atrial enlargement. There are limited studies to evaluate whether P wave parameters are independently associated with decline in renal function. Accordingly, the aim of this study is to assess whether P wave parameters are independently associated with progression to renal...
متن کاملSimulated Obstructive Sleep Apnea Increases P-Wave Duration and P-Wave Dispersion
BACKGROUND A high P-wave duration and dispersion (Pd) have been reported to be a prognostic factor for the occurrence of paroxysmal atrial fibrillation (PAF), a condition linked to obstructive sleep apnea (OSA). We tested the hypothesis of whether a short-term increase of P-wave duration and Pd can be induced by respiratory manoeuvres simulating OSA in healthy subjects and in patients with PAF....
متن کاملImpact of hemodialysis on P-wave amplitude, duration, and dispersion
Atrial fibrillation (AF) is a frequent arrhythmia in patients undergoing hemodialysis (HD). P wave duration (PWdu) and P wave dispersion (PWdi) have been shown to be predictors of emerging AF in different clinical conditions. We sought to study the impact of HD on PWdu, PWdi, and P wave amplitude in a cohort of patients undergoing HD. Seventeen patients (8 men, 31+/-10 years) were studied. Echo...
