Thanks to all your replies to my first post as a newbie, and all the advice I've read on the blog since, I had a good idea of what to ask for after I was diagnosed with PAF in December.
After initially trying me on beta blockers my very helpful GP was happy to refer me to an EP under the NHS and even researched where to send me - the William Harvey hospital in Ashford has an outreach clinic from guy's and St Thomas and that's where I was referred to.
I had my first EP appointment yesterday, I've been scheduled for more tests including 24 hour ECG, echocardiogram and heart scan to determine if I'm a candidate for ablation - something I wanted to pursue because I get quite severe episodes of AF and the beta blockers (bisoprolol at the moment) give me quite debilitating side effects. I've also been prescribed rivaroxaban rather than warfarin because my job makes the monitoring needed for warfarin impractical. All that, plus very helpful advice on how to manage episodes in the meantime. In fact it was all offered without the battle I was expecting and even without having to ask thanks to my GPs referral letter.
So far, so good, feeling much more positive now thanks to my GP and you guys out there for all your replies and comments, plus the information leaflets on the AF association website. Knowledge is power.
