Yes, there are lots of people on here who have had a low EF%. 

Did you have a specific question about yours?

keep an eye on it

I have an echo every year to keep an eye on it. A small percentage of paced patients see a drop in EF due to pacing. It can be treated, that's why we watch it closely.

There is a large variation with ejection fraction. There is a large variation with different centres taking measurments.


Even those with renal failure may have to take these measurements 'with a pinch of salt', as the saying goes. Even worse is the fact that there can be +/- 14% variability with the technicians taking the measurements.  A normal range of 55-70% indicates this variability.

I see that you're worried about your son and his EF. Please see your latest post.

I started at 18 years old, been doing this for 36 years and on device number five.   Somewhere around number two or three they started annual echos to keep an eye on my EF, first off with complete block, which I have, and then RV pacing the EF can drop and so they watch it.  Mine was not great to start, but when it got down into the 30s it was time for a biventrical, fortunately that did help and it is now higher than it has ever been.
