@danab I'm sorry, I do not understand your statement, Dana. What I was suggesting is that a pacemaker is meant primarily to speed a slow heart rate, but not to encourage the heart to beat more slowly. It can only regulate the HR in both directions IF....and only if...it isn't forced to contend with a wonky/blocked AV node. AV node ablation, meaning it gets destroyed with the same technique as a catheter ablation of atrial fibrillation (that is, with energy applied, and sufficient to destroy the AV node completely...it will never be active again) is done for SVT, severe AV node block, and atrial fibrillation where the patient can't be left in AF indefinitely....it must be stopped. You only had, I believe, a slow heart rate, and that is what a pacemaker is meant to improve...to speed up your HR to a programmed base level, say 62-65 BPM, depending on circumstances and need.
Would you mind terribly rephrasing your statement and I will come back and read that, hopefully to improve my comprehension?
