Hey, not sure if you got my message or not---please check the information I sent you about some of the meds you are on and interactions. This is very important.
good luck on the appt; if you're having presyncope or syncope issues then they need to find out why - ask about a tilt table test to rule out any ANS (autonomic nervous system) problems
with them finding that potassium & phosphate low that could be a problem and you may benefit from taking what they suggested, certainly ask the EP when you go their thoughts and see if it helps
the only med that has helped me has been Inderal; but that's only a short term mild duration and doesn't help with everything
I sent you a private message-you can check ur inbox---that way I dont offend anyone with my answers lol
Cant give you an answer to all your questions but I can wish you good luck for you visit with the EP.
Good Luck
