| Summary: | ABSTRACT Background Atrial septal defect (ASD) can lead to volume overload and related changes in P‐wave parameters in surface electrocardiograms of these patients. In this study, we aimed to evaluate the effect of volume overload on P‐wave parameters in patients with ASD. Materials and Methods This study is a retrospective cohort analysis. A total of 142 patients with secundum ASD who underwent percutaneous closure were evaluated. P‐wave duration (Pmax) and P‐wave dispersion (PWD) were measured on the surface ECG before and 1 h after the closure procedure. We evaluated P‐wave parameters in terms of defect size, duration of the volume overload, and closure device sizes. Results Pmax and PWD were significantly decreased after the procedure compared with the values before the procedure (p < 0.001). Pmax values had a statistically significant correlation with ASD size (< 20 mm or ≥ 20 mm) both before and after the procedure. Pmax values were significantly higher in patients older than 30 years of age (119.6 ± 19.5 vs. 102.7 ± 17.1 ms, respectively; p = 0.039). A significantly positive correlation was found between pre‐ and post‐procedural Pmax and defect sizes (r = 0.474, p = 0.019 and r = 0.4233, p = 0.04, respectively). However, no positive correlation between PWD and defect age and size was present. Conclusion Percutaneous closure of ASD is associated with an immediate decrease in both Pd and Pmax that seems to be related to the acute volume overload cessation in cardiac chambers. |
