and I have no ideas what the rules are
I have an ongoing diagnosis of a heart electrical issue, so nothing actually diagnosed or treatment yet
I was at a theme park when I collapsed during the day, staff came over and gave me a wheelchair to use, I also got to use the disabled access to rides as I couldn't stand in a queue for 30 plus minutes.
as I can still walk around most of the time and just feel weak when I have an attack is it OK for me to use a wheel chair when needed? last week I did a two mile walk with no issues 
also what are the wheelchair rules?
