Hi @fuzzlepuff,
I read a bit of your story in your other posts
- Unknown Heart Condition https://connect.mayoclinic.org/discussion/unknown-heart-condition/
- Sleep paralysis during naps https://connect.mayoclinic.org/discussion/sleep-paralysis-during-naps/

You mention that you've been seen at Northwestern in Illinois, so I assume you've requested an appointment at Mayo Clinic in Rochester, Minnesota. @roch is right that every stituation is different. I'm tagging a few other members like @karukgirl @jeanern01 @sall @jenniferhunter @dsisko who can share their experiences of getting an appointment at Mayo Clinic.

I’m sure you’re anxious to hear back from Mayo Clinic. Cardiology issues are very diverse and there are myriad factors to be considered when a referral has been placed. Your case information will be reviewed and then directed to a specialty care for review by Mayo specialists. So it may take some time before you receive contact.

@fuzzlepuff, did you self-refer or did your doctor submit the referral request? When you asked "Is it going to be a phone call or will it be on the portal?" - what is the "it" you are referring to? Have you made an account on the Mayo Clinic patient portal?
