Signal-averaged P wave analysis for delineation of interatrial conduction – Further validation of the method

BMC Cardiovascular Disorders, 2007
Background The study was designed to investigate the effect of different measuring methodologies on the estimation of P wave duration. The recording length required to ensure reproducibility in unfiltered, signal-averaged P wave analysis was also ...

Impact of hemodialysis on P-wave amplitude, duration, and dispersion

Indian Pacing and Electrophysiology Journal, 2007
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.

Differentiation of atrial tachycardia from other long RP tachycardias by electrocardiographic characteristics

Journal of Arrhythmia, 2014
Background: The incidence and electrocardiographic characteristics of atrial tachycardia (AT) among long RP tachycardias have not been fully elucidated. Methods and results: Thirty-six patients with 37 long RP tachycardias were classified as having AT (n=

Nebivolol And Quinapril Reduce P-Wave Duration And Dispersion In Hypertensive Patients

Indian Pacing and Electrophysiology Journal, 2009
We aimed to investigate the effects of nebivolol and quinapril treatments on P-wave duration and dispersion in hypertensive patients. Hypertensive patients who were in sinus rhythm were assigned to the two treatment groups and received either 20 mg ...

A Nomogram utilizing ECG P-wave parameters to predict recurrence risk following catheter ablation in paroxysmal atrial fibrillation

Journal of Cardiothoracic Surgery
Highlights Abnormal changes in P-wave parameters indicative of atrial electrical remodeling often manifest earlier than changes in other indicators reflecting atrial structural remodeling in paroxysmal atrial fibrillation. Preoperative absolute values of

Brain natriuretic peptide and P wave duration in dialysis patients

, 2007
Objectives P wave duration and dispersion, defined as the difference between the maximum and minimum P duration, are regarded as very important non-invasive ECG markers for assessing atrial arrhythmia risk. Plasma brain natriuretic peptide (BNP) level is
