Jess,
I have a young daughter,26 years old, who has AS and had to have a pacemaker put in last year. My grandson (age 7) has AS and just found out he has a bundle branch block. The doctor will watch him, if it gets worse they want to put in a pacemaker. I have AS, and so far my heart seems to be ok. I know there are several here at KickAS that have heart problems. Maybe you will be one of the lucky one who does not have any problems with your heart.
I think its worth while to have it checked out. With the family history, I have my checked about once a year with an EKG and an Echo.
Good luck,
Debora
