Pacemaker self test
My Biotronik pacemaker has been set to self test at 3:30 am. In the last year the time has been gradually getting earlier to the point that one month ago it was occurring at 2:30 am. In the last week, I experienced a light headed feeling each night about 10:30 pm. I had my annual pacer test last Thursday during which I told the technician of the recent events. He insisted that the pacemaker was set to test at 3:30 am and that I must be mistaken about what happened. Last night, I went to bed at 10:30 and felt the pacemaker performing its self test. No question about it. That was a 3 hour jump in when the test had been being performed. Has anyone else experienced this? Is there an explanation?
