I had my pacemaker implanted when I was 15, during an open heart surgery to perform a valve replacement
, so in July it will be 9 years old. I know I will have to have the battery
replaced anywhere between two months to 4 months from now. My pacemaker was implanted under my ribcage on my left side. I know the leads are still fine from my doctors okay but I do want to know what to expect and how invasive the battery replacement surgery will be?
