explanation

I have a CRT-D device from Boston Scientific. I have cardiomyopathy, LBBB, CHF, and have had by-pass surgery. They say that I am now paced 100% ventricles and 92% in the atria. Can someone explain about the pacing that is done this much? I've never asked the doctor to explain.

95% bi-ventricular pacing threshold

by cabbie - 2014-10-02 02:10:34

Hi. I have a Biotronik CRT-D for CHF with NIDCM and 2:1 AV block. I have been told that acceptable pacing threshold for both ventricles is 95%. Ideally, the closer to 100% the better so that there will be no intrinsic ventricular activity, just the bivent pacing from the CRT-D.

I have an intact SA node so I don't know about the atrial pacing threshold.

Hope that helps

I too have a CRT-D from BS. I have all your abbreviations plus SSS. I have not had by-pass surgery.

I am also paced 100% in the ventricles. As cabbie said, that is preferred for our condition. Our ventricles were not beating in sync....very inefficient and taxing on the heart and the rest of the body. The CRT corrects that.

I also pace similar in the atria as you. It can vary to what your heart needs....mine has been sometimes 92% and last check was 93%.

Don't be concerned about the % of pacing....you get what you need. :-) Go by how you feel.

Hope this helps.
