I just have a quick question for those with a pacemaker. I received my first pacemaker in 2002 after my heart transplant. I received my second in 2011. My last interrogation showed that I only have 15% battery left, about 9 months if I'm lucky. (I'm paced 95% in my atria). I have my original leads. Has anyone ever had their leads changed? I will have had these leads for 18 years in July. I'm going to ask when I see them in March about it, but I'm just curious about others. Thanks!
