Non-invasive electrocardiographic predictors of atrial arrhythmias in patients with the Fontan palliation
(2017) In Journal of Electrocardiology 50(5). p.576-583- Abstract
Background: Fontan palliation patients are at risk for atrial arrhythmias post-operatively. This study aimed to evaluate whether differences in depolarization vector magnitude or spatial P-R angle can reliably predict atrial arrhythmias in patients who had undergone Fontan palliation. Methods: A total of 115 patients who had Fontan palliation and post-Fontan catheterization were included. Atrial arrhythmias were identified in 14 patients. Measurements of ECG parameters including QRS vector magnitude, P-R duration, spatial QRS-T angle and spatial P-R angle were performed, and compared between those with and without atrial arrhythmias. Results: Only the QRSvm independently differentiated those with and without atrial arrhythmias with... (More)

Results: Only the QRSvm independently differentiated those with and without atrial arrhythmias with multivariate HR of 0.743 (95% CI 0.581 to 0.951). Conclusion: In Fontan patients, the QRSvm was the only significant independent predictor of atrial arrhythmias.
