A comparison of p-wave duration and dispersion in patients with short-term and long-term atrial fibrillation

Abstract: This study compared P-wave duration and dispersion (PD) in patients with short-term (< or =48 hours) and long-term (>48 hours) atrial fibrillation (AF) after cardioversion. We studied 96 consecutive patients with short-term (group A; n:51, age: 61 + or - 11 years) and long-term AP (group B; n:45, age: 64 + or - 10 years). P-wave measurements were calculated from 12-lead electrocardiogram. There was no difference related to clinical characteristics. Left atrial dimension was significantly higher in group B (P = .003). P maximum (124 + or - 12 vs. 113 + or - 11 ms, P = .001) and ...
