I have had a pacemaker since November 4, 2010. I would like to begin my hobby - Stained Glass but I wonder if glass cutting, soldering irons, lead tools, copper foil supplies, grinding equipment and grozing are objects I should avoid. I am 85 years old and 5 feet and 10 inches. I had a cardio version in May 2010 and was unable to breathe well immediately following the procedure. Two nights later a ambulance rushed me to the hospital. After two days in the hospital and many tests, I was scheduled for a pacemaker.
