Hi guys I'm having issues. In Sept I was having numerous palpitations and skipping beats. I went to the ER. They said seems fine. The pacemaker rep came to the hospital and interrogated thoroughly. At that time he said I had 5 years on my battery. 1 month later they said I had 2&1/2 years on my battery. Because of the ongoing heart rate issues I had to go back yesterday and they now tell me I have 6 mons and they want to replace the battery? How could I go from 5 yrs left to 6 mons in 3 mons time? Also in March they said I was only using my pacemaker 18% of the time ,up a mere 5% in a year. In September they said I was using it 34%. Yesterday they said 54%! OMG 18% to 54% in 9 mons ?????? What the heck? Could the pacemaker be malfunctioning??? Have you guys heard of anything like this??? Help???? Also the person taking my appointment for surgery, said that St Jude pacemaker's have a problem with quick battery depletion towards the end of the battery life. But mine isn't on the list of recalls?????
