“…Several studies have shown that prolonged SAPWD can affect the short-term and intermediate prognosis for AF relapse (11,14,17). In a recent AFFIRM-substudy, electrophysiological remodelling evaluated from the standard ECG (lead II P-wave duration135 ms) was associated with an increased risk of recurrent AF within 2 months of cardioversion (18).…”

“…In comparison with analysis of a standard 12-lead ECG, Guidera and Steinberg already in 1993 showed that the SAECG is superior in detection of P wave prolongation as a risk marker of AF (10). Later, prolonged SAPWD has been associated with AF in different clinical settings (11,12). However, the method has not yet been accepted in clinical use (13).…”

“…Prior studies have demonstrated that individuals with clinical history of paroxysmal AF (PAF) have a significantly longer intra-atrial and inter-atrial conduction time of sinus impulses, which was not only electrophysiologically determined [4,5,6,] but was also shown as P-wave prolongation on 12-lead surface ECG and signal-averaged ECG recordings [7,8,9]. The importance of P-wave dispersion (P d ) in predicting recurrence of AF in patients with PAF and after cardioversion was also elucidated [10,11,12]. But, however, we do not know the predictive value of P d for AF in patients undergoing PCI.…”

Atrial fibrillation (AF) may occur during or after percutaneous coronary interventions (PCI). The purpose of the study was to determine the clinical, angiographic and electrophysiological predictors of AF after PCI. 225 patients undergoing PCI (mean age of 65 ± 11 years) who had sinus rhythm (SR) before balloon inflation were taken to study. Of these 22 developed AF in catheterization laboratory after balloon inflation or in 24 h following PCI (AF group), 203 did not (SR group). The patients in AF group were older (67 ± 9 vs. 63 ± 8 years, p < 0.05) and their ventricular ejection fraction was lower than SR group (56 ± 5 vs. 45 ± 7%, p < 0.05). The P-wave dispersion was significantly higher in AF group than SR group (53 ± 8 vs. 29 ± 10 ms, p < 0.001). For the patients with ST elevation myocardial infarction, the time from the onset of symptoms to balloon inflation was 3.7 ± 1.7 h in SR group. It was longer in AF group (4.1 ± 1.8 h, p < 0.05). TIMI perfusion grades 2 and 3 were achieved in 23 of 27 patients in SR group, and 5 of 8 patients in AF group. Multivessel disease was documented in 93 of the patients in SR group, and 12 in AF group. Clinical reperfusion was thought to be established in 20 in SR group, and 4 in AF group. In conclusion, our results show the importance of clinical factors, angiographic results and P-wave analysis in prediction of AF following PCI.

The atrial electrical signal or P wave is becoming more widely studied because of the large incidence of atrial arrhythmias. There are few reporfs guantzfiing the spatial distribution of atrial signal amplitude in the 12-lead ECG. Our aims were to quantify the spatial distribution of atrial signal amplitudes in groups of healthy subjects and patients with atrial fibrillation, and to develop a simple model of atrial depolarisation based on a single dipole. Amplitude was significantly smaller ( p < 0.05) in leads I, Ii, aV,, aV,, V5 and V6, and significantly larger in lead VI in atrial fibrillation compared with those of the healthy group. A single dipok model was able to qualitatively simulate the body surface atrial elecmrical signal in specific subjects from these groups.

P Wave Amplitude and Duration may Predict Immediate Recurrence of Atrial Fibrillation After Internal Cardioversion

Abstract: As a result, the incidence of IR of AF after IC was higher in the patients with shorter P wave amplitude (for lead II P<0.01, for V1 P<0.01) and larger P wave duration (for lead II P<0.01, for V1 P<0.05).
