Prevalence of Bundle Branch Block and Axis Deviation in Permanent Atrial Fibrillation and Gender Differences

There is a correlation between atrial fibrillation and left bundle branch block. The presence of left bundle branch block could be a risk factor for atrial fibrillation and the presence of left axis deviation could be a protective factor. There is no difference between female and male patients. There is a difference in the age group; young subjects with atrial fibrillation have a significant correlation with left bundle branch block, which may demonstrate a poor prognosis for patients with atrial fibrillation.
