youngmom - I am another member who wasn't expecting to have a pacemaker, yet I do. I had long-standing aortic stenosis and after valve surgery my heart tried any and every combination of rhythm. It went fast, it went slow. It went into afib, tachycardia, bradycardia - then it just stopped, taking pauses of up to 20 seconds. It is not a good thing to see your own heart monitor screen go flat-line, let me tell you. My pacemaker was implanted a few days after surgery, and with one minor exception (tech botched a setting), I haven't looked back. I don't even realize it is there unless I look in a mirror with my shirt off. I am in the gym 5 days a week, ride my bicycle, work on home repair/improvements, lift weights - I do more than most folks my age. No restrictions. You may have some frustration the first few months getting all the settings right, but after that I didn't even notice it. For the first few weeks you cannot raise your left arm over shoulder height, but after the leads are all healed into position, there are no restrictions about range of motion, either. Don't worry about the pacemaker - ignore it. Go on with your life. That's what the pacemaker is there to allow.
Agian - Most pacemaker patients can see their devices just under the skin below their collarbone, on their left side. They are most obvious in thinner patients, but the new devices are much smaller than they were a few years ago. After the leads heal into place (around 4 weeks) there are no range-of-motion restrictions. I just live my life and have it checked twice a year to be sure.
BTW - Don't be terror-stricken about all the warnings regarding electronic devices, either. I even operate a 100-watt amateur radio transmitter with no issues. I travel (ask for manual security check, avoid the metal detectors, back-scatter scanners are OK), drive a car, operate electric tools. Heck, I work in a manufacturing company. I work in the office but often go out into the factory where there are all sorts of big electric and electronic machines running - all with no effect on me.
