I just noticed your posted question and see that it is dated from over a year ago. Did your dad get his pacemaker? If so, I am sure that he is doing fine and even better than before. I am 42 years old and ironically, on Dec
16th, 2009 (the day after your question was posted) I was having emergency heart surgery to implant a dual-chamber pacemaker. It has changed my life. Yes, there is a lot of things to learn and adjust to, but it is so very worth it. Good luck to you and your father!
