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.

期刊介绍： The ANNALS OF NONINVASIVE ELECTROCARDIOLOGY (A.N.E) is an online only journal that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. ANE is the first journal in an evolving subspecialty that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. The publication includes topics related to 12-lead, exercise and high-resolution electrocardiography, arrhythmias, ischemia, repolarization phenomena, heart rate variability, circadian rhythms, bioengineering technology, signal-averaged ECGs, T-wave alternans and automatic external defibrillation. ANE publishes peer-reviewed articles of interest to clinicians and researchers in the field of noninvasive electrocardiology. Original research, clinical studies, state-of-the-art reviews, case reports, technical notes, and letters to the editors will be published to meet future demands in this field.
