Background Bariatric surgery has been associated with reduced cardiovascular mortality and morbidity in obese patients. In this study, we aimed to evaluate the alterations of novel P-wave related atrial arrhythmia predictors in patients who achieved effective weight loss with bariatric surgery. Methods The study included 58 patients who underwent bariatric surgery. We measured heart rate, PR, P wave (PW) max, PW min, Average P axis, P wave peak time (PWPT) in lead D2 and lead V1, terminal force in lead V1 (V1TF), and we estimated P wave dispersion (PWdis) interval both pre-operation and 6 months after operation. Results Heart rate, PR, PW max, PW min, PWdis, Average P axis, PWPTD2, PWPTV1 and V1TF values, which were close to the upper limit in the pre-op period, showed statistically significant decreases at 6 months after the operation. The most prominent changes were observed in PW dis (51.15 +/- 9.70 ms vs. 48.79 +/- 9.50 ms, p = .010), PWPTD2 (55.75 +/- 6.91 ms vs. 50.59 +/- 7.67 ms, p < .001), PWPTV1 (54.10 +/- 7.06 ms vs. 48.05 +/- 7.64 ms, p < .001) and V1TF (25 [43.1%] vs. 12 [20.7%], p < .001). Conclusions The results of our study indicated that bariatric surgery has positive effects on the regression of ECG parameters which are predictors of atrial arrhythmias, particularly atrial fibrillation (AF).
