Went to the doc yesterday and the Tech Rep for the company that makes my pacer checked it out and tweaked the voltage. He is giving me a Computer Gizmo to connect directly with him for downloads and monitoring. He changed voltages to show me how it affects the heart rate and, as the flesh heals, a different resistance will be there, so they do tweak the voltage. The trade off is battery life and they don't replace the battery, they replace the whole thing. Lots of stuff to absorbe about this new fuel control.
