It occurs in up to 40% of patients primarily within 2 to 3 days, and it can compromise systemic hemodynamics and increase the risk of embolization. Some clinical issues can predict the risk of atrial fibrillation, like P wave duration. The aim of this study is to evaluate the role of P wave duration in prediction of post cardiac surgery AF.Methods: We measured P wave duration in 206 cardiac surgery patients the day before surgery and followed the patients for 3 days to find the possible relation between P wave duration and the risk of AF after surgery.Results: Our study showed the prevalence of AF after cardiac surgery was about 9% and there was no relation between P wave duration before surgery and risk of AF after surgery.Conclusion: The risk of AF in our patients was less than other studies, and this study showed we can not use P wave duration in surface ECG as a predictor of post-cardiac surgery AF.}, keywords = {Atrial Fibrillation,Cardiac Surgery,P wave}, url = {http://journal.iha.org.ir/article_84070.html}, eprint = {http://journal.iha.org.ir/article_84070_603f5a0c310870eee6d51b448fd99aed.pdf} }
