It was strange my P.A. Pace nurse kept telling my not to play tennis or go fishing after my ICD/Pacemaker was put in regardless of waiting 3 months. She said it is the violent jerking of arms that they trace back to see what activity caused it and sees it is the violent jerking where she sees wires coming loose.

My EP was the opposite. Go play tennis (after 3 months). It is why we put the ICD/pacemaker in for you to enjoy the sport. Should have listen to the P.A.

But they did put a new wire in and remove the one that came out. But I had to have a surgeon do it and they went in through my side, deflated lung, and put directly on heart. I started playing tennis again after I healed and all was okay for several years. Then started having noise and problems with conduction on the wires. I stopped playing tennis after one day got my first taste of a ICD shock.

They tried to tell me most likely electrolyte issue but I think I just was pulling the wires too much and caused some irritation of the heart muscle. I have no idea it that is correct and surely I have no medical background to say it was but for me I no longer wanted to take a chance.
