Possible left atrial enlargement / Boarderline abnormal, Bradycardia

I was sent in for EKG with an exercise stress test before my scheduled elective surgery.  The tests came back saying Boarderline abnormal, Bradycardia. EKG also said sinus arrhythmia possible left atrial enlargement.  My question is my surgery is in 5 days, should I find out what is actually going on with my heart before going for surgery?  The surgical facility has my results and said all was good to go. How concerned should I be?

If the abnomalities are borderline there is no need for immediate action and as the surgeon said, no problem for your upcoming surgery. I suggest that you have that surgery first.

After that, it might be a good idea to contact a cardiologist to get more info on the bradycardia and the LA enlargement.
-Note that a slow heart rate is often no problem and only needs treatment is symptoms from it become severe like fatigue, weakness, dizziness or fainting.
-LA enlargement is indicated from the EKG. A reliable measurement for LA can however not be derived from EKG.
To get a good idea of the size of the LA, an echo is the best way to measure its size and, if indeed enlarged, to check what might have caused it.
