I can speak to this as I’m just going through it now.
I’m a young male in good health. I started having weird heart palpitations randomly starting last year. Had them four times, but they normally go away after 20ish mins. GP reviewed me, said it seemed fine, but to go in to ER if anything about them changed (ie more frequent, more intense, lasted longer).
Last friday they went on for an hour, so I went in. Entered at 11am.
Was triaged within 15mins, including an ECG. Once they confirmed it wasn’t an active heart attack, I sat in the waiting room for two hours. I then saw a doctor, got a chest X-Ray, and bloodwork taken within 45mins. I proceeded to sit in the room hooked up to the vitals monitor for four hours while they ran my bloodwork, and the ER doc came back. He sent me a requisition for a cardiologist and told me to take aspirin until I saw the specialist.
I saw the Cardiologist on Wednesday, and he’s explained he’s not concerned given my lack of other risk factors. He’s now sent me over for an ultrasound and 36hr halter monitor next Monday. He said unless something weird comes back or he wants another test, he won’t see me again, and I should follow up with my GP 2 weeks after I finish the halter monitor.
So within 3 or 4 weeks I had a full range of tests done, and my biggest expense was $7.50 parking for the 30min cardiologist appointment, which I was actually unironically complaining about to my wife last night.
