Gentlemen, and ladies, I had open heart triple by-pass surgery. My heart is operating at approx 25%. My cardio rehab said they could raise my heart function % with rehab. My surgeon wants to install a Defib. I would like responses from anyone who has had one installed or that knows someone and the results. I hesitate having wires implanted that I understand can't be removed. I also understand I will have to alter or modify my way of doing some things, such as wearing a leather jacket to weld, not having any electrical device close to the defib. I'm 82 and normally very active. Any and all opinions are welcome. Thanks, James C.
