Simulated 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 کاملP 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 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 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 duration and dispersion analysis: methodological considerations.
Methodological Considerations To the Editor: With great interest, we have read the article of Fan and colleagues1 on the effects of biatrial pacing in the prevention of postoperative atrial fibrillation after coronary artery bypass surgery. By measuring P-wave duration from 12-lead surface ECGs and calculating P-wave dispersion, they found that biatrial pacing resulted in a more significant red...
