Hi, Gary.
If you read my message, please register for the forum. It's free of charge or any kind of hassle, and it's easy to do. Here's a link to a brief video that walks you through the registration process:

The advantage of registering (at least one of them) is you'll be able to read and reply to comments in this thread and others. And, yes, I'm pretty sure you'll get plenty of comments.
Here's mine in a nutshell: No, don't do it, at least not yet. A/V node ablations have their place, but not for an active and healthy-sounding 81 year old. Instead, seek out an EP like Dr. Andrea Natale in Austin, Texas, who has tons of experience successfully ablating old and young patients. It may take a couple of procedures, but you're likely to be a-fib and flutter-free (and highly functional) afterwards.
