Yes there are hoops to jump through and some conditions will simply be a non starter, but if you can manage with acceptable pacemaker settings you should be OK. The tests can be pre booked and done in just over a day. I don't see how anyone can justify £1000 especially as most of the tests are needed as part of routine follow up. Sadly some doctors see the word pilot and think it reads cash cow.
Happy to help on this off thread
