They were pretty confident of the diagnosis they were to confirm. In
the process of
testing ( which consisted of
adenosine, then recovery/opening with acetylcholine) I arrested and it took them a couple of minutes to get me back. I was awake/conscious for
most it and was even pleased when the docs were able to reproduce my symptoms! Unfor
tunately the recovery drug just didn't work therefor
e the confirmation of cardiac microvascular dysfunction.
