Association of atrial fibrillation and various cancer subtypes.

Background: Studies have shown that the incidence of atrial fibrillation (AF) in cancer is most likely due to the presence of inflammatory markers. The purpose of our study is to determine the association of AF with different cancer subtypes and its impact on in-hospital outcomes.

Methods: Data were obtained from the National Inpatient Sample database between 2005 and 2015.

Association between atrial fibrillation and bundle branch block.

Background: The association between atrial fibrillation (Afib) and sinus and AV nodal dysfunction has previously been reported. However, no data are available regarding the association between Afib and bundle branch block (BBB).

Methods: Patient data were obtained from the Nationwide Inpatient Sample (NIS) database between years 2009 and 2015.
