@ejbb You have certainly covered all of the bases! Waiting and waiting for your appointment is frustrating ((HUG)). I can share that a few weeks after my septal myectomy, I experienced dizziness and giddiness and ended up with an ICD that I named Buddy to eliminate the arrythmias that developed. You will see an electrophysiologist (good!), it will be good to find out if it's a heart electrical problem and what recommendations are made. I have a suggestion: call the offices where you are scheduled to go - often - even daily - to see if there are any cancellations. That has worked for me and others - I've even "gotten in" later the same day. Easier for the scheduler who does not need to search for the wait list.
