Signal averaged P wave compared with standard electrocardiography or echocardiography for prediction of atrial fibrillation after coronary bypass grafting.
OBJECTIVE To define the clinical value of the signal averaged P wave (SAPW) and to compare it with the standard electrocardiogram (ECG), echocardiogram, and clinical assessment for the prediction of atrial fibrillation after coronary bypass grafting (CABG). DESIGN Prospective validation cohort study. SETTING Regional cardiothoracic centre. PATIENTS 201 unselected patients undergoing first...
متن کاملAtrial fibrillation after coronary artery bypass grafting
Postoperative atrial fibrillation (POAF) is the most common complication following cardiac surgery with an incidence of 18.5–40 % [1–4]. It is important to prevent POAF because it can lead to hemodynamic instability and the risk of cerebral infarction. Various factors are involved in the onset of POAF, among which those most strongly correlated with it are inflammation, fibrosis, and the fluid ...
متن کاملSignal-averaged P wave in patients with paroxysmal atrial fibrillation.
The theoretical and experimental rational of atrial signal-averaged ECG in patients with AF is delay in the intra-atrial and interatrial conduction. Similar to the ventricular signal-averaged ECG, the atrial signal-averaged ECG is an averaging of a high number of consecutive P waves that match the template created earlier P wave triggering is preferred over QRS triggering because of more accura...

متن کاملAssociations between preoperative P-wave characteristics, C-reactive protein levels, and atrial fibrillation after coronary artery bypass graft surgery
Introduction: Atrial fibrillation (AF) is the most common complication of cardiac surgery which may cause remarkable morbidity and complications. Identifying predicting factors of this arrhythmia can help prophylactic therapy. The present study is designed to investigate the hypothesis that HsCRP level and P-wave characteristics are associated with the incidence of post-operative AF. Methods: ...
