Under sensing problem
I had some complications because of difficulty accessing the vein during initial pacemaker placement 4.5 weeks ago. As a result, the ventricular lead is under sensing my natural heart rate. A few days post-op, the pacemaker clinic said the lower lead was only sensing at 40% "sometimes". They reassured me that it is not dangerous and can be resolved a few different ways but that they will recheck at the 6 week mark. They confirmed that the pacemaker is working "well enough" to fully resolve my AV block.
Needless to say, I'm anxious and disappointed that things are not working 100%. It's bad enough needing a pacemaker and having a difficult surgery with a long, painful recovery.
My questions for the forum are:
1. Has anyone had a sensing problem that improved between week 0 and week 6?
2. Has anyone needed to have the sensing threshold adjusted to resolve under sensing?
3. Under what circumstances do they decide to operate and try to improve lead placement?
4. How bad is lead repositioning surgery?
I'm mostly doing a good job of putting this out of my mind and visualizing point #1 above. It's a challenge though!
