ERI and voltage
My pacemaker is 11, almost twelve, years old. We've been doing more frequent checks for about a year. At the most recent in-office check a couple of weeks ago, I was told my pacemaker is now in ERI because the voltage is at 2.6v, although the estimated battery still reads 2-3 months.
Although I've noticed voltage increasing in the last year or so, I'd never thought to question its significance to ERI. But now I'm curious. What is voltage telling us?
Also, although no mention of the need for it was made during the pacemaker check appointment, my EP has ordered an echocardiogram. Again, I am wondering about the significance. Does an increase in voltage suggest a possible change in the heart's (rather than the pacemaker's) function?
