Very good news that you are on the mend. As one who has undergone a heart ablation (2+ years ago), I can assure you that following the Dr's directions - and thinking for yourself - offer the best options for a full and active lifestyle going forward. I am in Pittsburgh and agree with your "shout out" to the doctors and facility personnel - same here!
Be sure to keep the lifting under the 20 pounds, enjoy your "relaxing" time, and stay well.
