Fran- what kind of Arrhythmia did you have- do you know specifically? Sometimes, left sided heart failure can extend to the right, but RA enlargement can also occur with regurgitation, tricuspid valve problem, or with something like untreated A-fib.
Here is a link with a list of info for you. I haven't looked at any of them yet, but it's emedicine.com, so it's reputable:

I hope you feel better soon. Please take care of yourself, and let us know how your echo turns out. We love you, Fran!
