I read with much interest the responses from donr and Inga to vattens1 about the lines on the Medtronic card. I hope you all can help me understand battery life. My Medtronic is a year old. my last four pacer checks say Dec, 2013 6 years battery life (at that time device is 2 months old). March 2014 I am up to 10.5 years. June 2014 10 years. November of this year I am down to 6.5 years! I am pacing at 2.2%. I looked at battery voltage and the sequence for that time period went: 3.04v, 3.04v, 3.03v, 3.02v. It is decreasing, but steadily, not like the projected battery life which actually increased when the voltage decreased. The most distressing part is the 6.5 years is the average of 4.5-8.5 years. I have had lots of issues with this thing since the beginning. I would like to believe that I am not going to be back in for replacement sometime unexpected. In other words, why can't they have a better certainty on battery life?
thanks in advance for all your amazing help. This site is a life saver for me.
p.s. my rep is very unhelpful at explaining anything
