thank you very much for the info, I havent had any other attacks since that day so Im still confused as they never gave me any ideas about what might have caused it, but I had another ekg performed a couple weeks ago and it was good except for a minor abnormality in the P wave , Im not as freaked out as I my Cardiologist wants to do another echo in six months so im hoping to here good things after that test, by me quiting smoking my resting heart rate and blood pressure are way lower ! so my heart doesnt have to work as hard, I am however still lifting weights
An echo estimates chamber sizes so although the report indicates enlargement it may be within the margin of error. Concern would be the size of the enlargement left atrium and the underlying cause for a larger deviation from normal size that can lead to problems ranging from electrical dissarray such as atrial fibrillation and there is a danger of clots (A-fib can cause blood to pool rather than pumped into the left ventricle.
Medications such as Beta Blockers and anti platlet medications may be administered to reduce the chances of any risks.
A common cause of afib is hypertension. Over time, hypertension increases the left atrial size and pressure within the left atrium that causes some scarring, and the scarring predisposes a patient for atrial fibrillation. Some people have primarily an electrical problem with their heart that causes afib. I don't see a connection with afib causing LA enlargement.
