I was initially quite angry, I did feel like questioning her however as a 17 year old I didn't know whether it was my place to do so. So of course I willingly went ahead and did everything she asked. I told her my family has no history of heart failure and as you say, my blood pressure had dropped into the 50's after I fainted.
I went back to my AME who did my Class 2 for advice and he sent me to the right person, albeit the extra tests cost double that what I paid for the initial. Without a doubt I will be going to my local AME for my Class 1 renewals, its just such a shame there are few places you can get your initials at.
