I am being. Upgraded to a crt-d from an icd. Has anyone experienced an improved ef after installation?
There is good published work showing that CRT works - not for everyone, but it definitely can make a real difference to patient health and not just numbers like percentage LV ejection fraction (%EF). %EF is a great objective assessment for the EP docs, and done by the same operator over a period of time, it's valuable. There is a quite a lot of variability in the measurement, and between operators, so small changes (a few percent) can be misleading, although long-term trends are reliable.
But what really matters is how you feel - and CRT works.
I'm a recent upgrade to CRT-P from a dual chnaber pacemeker.
Feelign good. Doing a lot of running for whihc I'm still getting seom tweaking of settings.

I had a pacemaker since 2002 and ever since then my life has been a total blessing.
