I have a Left atrium enlargement with a 1st degree heart block is there any cause for concern?

LA enlargement is likely due to one of several causes including high blood pressure, valve disease or other structural heart problems. This could be related to the first degree heart block since if the atria is big then it may take longer to conduct from the atria to the ventricle. The best way to evaluate LA or left atrial size is by an ultrasound or echocardiogram of the heart.
