Yes, the laymen explaination is not very good. It sound like she has A-FIB caused by a defective heart value. AND we all know from the endless TV commericals that medication can not treat this type of arrhythmia.
IF...she does have A-Fib....and she's was "worked up"...I'm sure she is being treated.
That all said....I could care less.....about her.
