I have an irregular heartbeat Chickadee and I am generally well apart from being a migraine sufferer. I have never had any issues with it, but it may just be an individual thing. Hope all goes well :)
mr mac had atrial fibrillation which is a form of irregular heartbeat and it made him feel absolutely awful chickadee - so it is possible but as sqad says, it depends.
When I had that problem I was given the electric pad shock on the chest, but it didn`t help so I was given a pacemaker which does the job and keeps on working for the last eight years.
