Apologies Radgirl, what I meant was Electro Physiology, my error. And for the record, I was directed to a Cardiologist 4 years ago who had operated on a colleague and fitted a stent. When I spoke to his secretary about my issue, she said I needed to see someone who specialises in Electro Physiology rather than one who specialises in Interventional Cardiology. So, if that particular medical secretary misspoke, then it appears I have been furnished with the wrong information.
It's nice to see that PPRuNe is still a bastion of self righteousness. No wonder I wandered off into the wilderness years ago...............
