I was reading about the battery changes... one thing I don't know is... If they need to temporary pace during a pacer change... HOW do they do it? Anybody know? Is is transvenous or AP external paced? It should be a while before a need a generator change. I know though.. the more work the pacer does, the quicker I will go through the batteries. What was put in as a back-up pacer has taken over 80% of the overall pacing. It has been the highlight of 2008. I am thinking of a next procedure if possible to removed the other 20% from my heart and hopefully not have to take the flecainide, diltiazem, coreg, lisinopril... anymore. Taking all those WITHOUT any high blood pressure to start out with has been fairly devastating. Any thoughts, any history, any wisdom out there?? Thanks.
