Predictive Value of P-Wave Dispersion for Paroxysmal Atrial Fibrillation in Healthy Elderly
By Şahin YB, Seçkin Ö
Background: Paroxysmal atrial fibrillation (PAF) is a common but frequently underdiagnosed arrhythmia in the elderly. Identifying noninvasive predictors in clinically low-risk individuals may enable early detection and prevention of complications such as stroke. This study aimed to evaluate the predictive value of baseline P-wave dispersion (Pd) and left atrial volume index (LAVI) in predicting PAF in healthy elderly patients. Methods: In this retrospective study, 385 patients aged ≥65 years without structural heart disease or major comorbidities were evaluated. All underwent baseline 12-lead ECG, transthoracic echocardiography, and 24-hour Holter monitoring. Patients were grouped based on the presence (n=47) or absence (n=338) of PAF. Pd and LAVI were compared, and univariate and multivariate logistic regression analyses were performed. ROC analysis assessed the diagnostic performance of Pd. Results: PAF patients had significantly higher Pd (48.8 ± 6.1 ms vs. 31.7 ± 5.0 ms, p
