Abstract :Objectives: Catheter-related atrial fibrillation insert ignore into journalissuearticles values(AF); is a common cause during electrophysiological study insert ignore into journalissuearticles values(EPS); and prolongs the duration of the procedure.  In our study, we compared P wave duration and dispersion in patients with and without catheter-related atrial fibrillation during EPS. Methods: One hundred forty five patients who had normal EPS findings and who were found to have catheter related atrial fibrillation were included in our study. Electrocardiogram was performed in all patients and the pulse rate, the longest P wave duration insert ignore into journalissuearticles values(Pmax);, the shortest P wave duration insert ignore into journalissuearticles values(Pmin); and the difference between of those insert ignore into journalissuearticles values(P wave dispersion: Pdisp); were recorded. EPS was performed in all patients. The patients were divided into two groups as the group 1 insert ignore into journalissuearticles values(without catheter-related AF); and group 2 insert ignore into journalissuearticles values(with catheter-related AF);. Results: In group 2, EPS time was significantly longer, Pmax and Pdisp were found to be significantly higher, Pmin was found to be significantly lower. Binominal logistic regression analysis revealed that, Pmax insert ignore into journalissuearticles values(OR: 1.077, 95% CI: 1.043-1.112, p < 0.001);, Pmin insert ignore into journalissuearticles values(OR: 0.889, 95% CI: 0.853-926, p < 0.001); and Pdisp insert ignore into journalissuearticles values(OR: 1.125, 95% CI: 1.080-1.173, p < 0.001); were all independent predictors for catheter-related AF. In ROC analyses, Pmax cut-off value of 120 ms determined the catheter-related AF with 61% sensitivity and 67% specificity, Pdisp cut-off value of 35 ms determined the catheter-related AF with 80% sensitivity and 71% specificity. Conclusion: Patients with longer Pdisp and Pmax and shorter Pmin may develop catheter-related AF during EPS.
