Effects of P‐wave Dispersion on Atrial Fibrillation in Patients with Acute Anterior Wall Myocardial Infarction

Abstract

Although P maximum and P dispersion are significant predictive factors of AF in patients with acute anterior wall MI in the univariate analysis, on the basis of multivariate analysis, only age and LVEF were independent predictive parameters for AF.

Prediction of Reperfusion and Infarct Related Artery Patency after Thrombolysis in Acute Anterior Myocardial Infarction by Degree of P Wave Dispersion on ECG

“…5 The study conducted by Baykan, et al showed that P wave dispersion was significantly higher in patients with AF than in patients without AF (P = 0.01). 12 Similar other study showed that P dispersion increased significantly during spontaneous angina (P < 0.001). 10 P wave dispersion was significantly higher in 60 patients with paroxysmal lone AF than in 40 healthy controls (p <0.0001) in another study.…”

Early electrocardiographic evaluation of atrial fibrillation risk in beta-thalassemia major patients

“…PD is a noninvasive indicator of intra-atrial conduction heterogeneity producing substrate for reentry, which is a pathophysiological mechanism of atrial fibrillation [16,17]. PD has been studied in some other conditions such as hypertension [18], obesity [19], diabetes mellitus [20], metabolic syndrome [21], dilated cardiomyopathy [22], myocardial infarction [23], atrial septal defect [24], hypertrophic cardiomyopathy [25], obstructive sleep apnea [26] and Wilson's disease [27]. The exact mechanism of PD prolongation in these clinical conditions is not well known, but it is thought that structural and electrophysiological changes in the atrial myocardium caused by elevated plasma volume [28], ventricular diastolic dysfunction [29] and enhanced neurohormonal activation [30], that accompany these diseases, may contribute to left atrial enlargement and electrical instability.…”

Assessment of left ventricular function by Doppler tissue imaging in patients with atrial fibrillation following acute myocardial infarction

“…It is shown that P wave durations and P wave dispersion on electrocardiogram both measured in a very early period of acute 0167-5273/$ -see front matter D 2004 Elsevier Ireland Ltd.

It is also shown that both advanced left ventricular systolic and diastolic dysfunctions are frequently associated with the occurrence of atrial fibrillation following acute myocardial infarction [8,13,14].…”
