That has been my experience. I've walked into an ER twice with heart palpitations. The first time I had an EKG, chest x-ray, and specialist consult and was in and out within 45 minutes. The second time was more serious and I was admitted, treated, seen by a cardiologist, and sent to a cardiac ward for overnight monitoring without being taken off the gurney. I know people who have walked in to their GP to investigate a lump in their breast and been under the knife a week later. They don't mess around with serious time-sensitive stuff.

But I have heard that the wait time for old people who need hip or knee replacements is quite excessive.
