pacemaker programming

After having a heartbeat of over 200 and a chord breaking on my mitral valve I had a mitral valve repair and a maze to stop the one time afib when the chord broke on the valve. Before the operation my sa node worked after it did not. They put in a saint jude pacemaker to only fire the top chambers. Well now when I work out the adrenaline comes in the av node makes the lower chambers faster then the uppers being paced at 75. This is making the pumping of blood out of sync, how is this fixed? Even if the speedup mode the acellerator is on the adrenaline is still going to make a un safe not synchronization upper and lower chambers miss match.

single lead pacing

The DANPACE trial, which was published after the publication of NICE Guideline TA88, has provided additional evidence comparing dual‑ with single‑chamber atrial pacing for people in your situation.

In a nut-shell you should have a dual chamber PM for the very reasons you outline, viz. synchronisation. Quite a few single lead patients end up having to have dual pacing.

New NICE guidelines came out in the UK last month. If you search ( upper right box) I have given a fuller account a couple of weeks ago.
