My dad for about the past 3-4 years has these "episodes" when he does anything exerting energy. It usually always happens outside doing relativley simple tasks like weed zapping, doing the lawn etc. In the past 2-3 years it's happened about 6-7 times. What happens is out of nowhere he'll just pass out with no warning or anything. He's completley out of it for 2-3 minutes and we have to keep slapping his face and yelling his name to get him out of it. He usually gasps for air for a couple seconds and then he's fine again. Once he's up he's completley normal and thinks nothing has happend. It's incredibly scary to witness. He's been to every doctor and had every test run on him, and finally his cardiologist yesterday said he thinks he needs a pacemaker because his heart beat is a little too slow and when he does exercise like this it makes him pass out. I know very little about pacemakers, and suprisingly I haven't find much information on-line. So if anyone has one, or knows someone who does I was wondering if you could give me some information. i.e. Any complications, how long it takes to install, was it an actual surgery or just done locally, is there recovery time? etc. First hand experience is always better to learn from. So any help would be greatly appreciated!
