UNASSIGNED: @entity616 ( @entity616 ) represents delay or block of conduction between the atria. @entity616 has been shown to predict the development or recurrence of @entity955 ( @entity955 ) in various clinical scenarios. Few studies have examined the correlation between @entity453 and the prevalence of @entity616 and its impact on @entity955 . The aim of this study was to determine if specific @entity453 (location and number) are associated with the presence of @entity616 and development of new-onset @entity955 . Retrospective analysis of @entity1 presenting with @entity583 ( @entity583 ) to our institution. Data were recorded for clinical, echocardiographic, angiographic, electrocardiographic, and outcome variables. Semiautomatic calipers and scanned electrocardiograms at 300 DPI maximized  * 8 were used to measure P-wave duration, with a follow-up for a minimum of 1 year. The chi-square and independent-sample t tests were done using IBM SPSS. A total of 322 @entity1 were included in the analysis. @entity1 72.3%, mean age 65.4      11.9  years, mean ejection fraction of 55.2    12.7% and mean left atrial diameter of 38.7    6  mm. The prevalence of partial @entity616 was 31.9%, and advanced @entity616 was 6.5%. @entity1 with @entity616 were significantly older (<0.001) and had a greater prevalence of @entity101 (0.014). The presence of @entity453 defined as >1 significant @entity453 was associated with @entity616 (0.026). No specific @entity453 location was found to be associated with @entity616 nor increased P-wave duration. @entity1 who developed @entity955 during the follow-up had a significantly higher prevalence of @entity616 (p  = 0.021) and also higher prevalence of @entity453 (p = 0.001). @entity616 is significantly associated with @entity453 in @entity1 with @entity583 . @entity616 is significantly associated with the development of new-onset @entity955 within 12 months after @entity583 .
