The only thing that worries me is your AME grounded you whilst awating the review of your ECG by the CAA. As far as I am aware this also covers your class 2 untill a cardiologist at the CAA has looked at your ECG readout.If he says its nothing then he will contact you and say so.
May I sugest you contact the CAA by phone or e-mail to clarify this and not rely on the website or hearsay.
Sorry about this but I have been there a number of times.
