VVI 40 from DDD
I have 2:1 heart block and a long PR interval
For most of this year I have been on DDD with rate adaptive AV.
the rate adaptive setting appeared to be the only way of me getting 1:1 pacing when exercising. This also included an upper tracking rate of 180bpm. Everything seemed fine no symptoms of anything even during my limited exercise events this year.
But this has meant I now pace 100% in the ventricles.
Last week after an appointment I was moved to VVI40. This was quite a surprise to me as it was effectively turning my pacemaker into a pure safety device nothing else.
I am going to see how this goes over the next month but has anyone been switched like this before?
