I also wanted to ask if a dipped chest can cause a left atrial enlargement.
I am 22, Female.
The report says "possible" right atrium enlargement. I would think an echo should be organised to make sure. Are you on any form of medication for anything? Your heart rate seemed to be pretty fast during the EKG, was you very nervous or something?
Your left part of your heart is enlarged it can be a natural accurance but if I was you id get the doctors to explain it my left ventricle is enlarged and i didn't know what it meant but ask them as they can explain it better or if your still worried about it go on google and type it in and it will give you answers
sorry I misread. Left atrium enlargement is usually the mitral valve not functioning correctly. An echo scan would find the cause.
