I think what frustrates me the most about "EMS" is the absolute abuse/misuse of the system. The majority of the patients I see (and I see a lot, I would estimate we're in the upper 10% for run volume across the country) are generally non-emergent "I've been feeling ill for a week".
Unfortunately, you're going to see a lot of that working in hospitals as well, especially in the ER. I've read blogs by ER doctors (like this one,
"M.D.O.D.") who are very burned out by it.
But if you avoid the ER and work upstairs in the hospital, you could be bored out of your mind. As a medic, you're used to a fair amount of action and movement, but you could be stuck emptying bedpans. Look before you leap.
My thought of going into ICU nursing was that at least there, the patients need to be there. Seeing high acuity patients every day instead of rarely might be more satisfying.
Hate to be the messenger, but the ICU is another major burnout area for medical professionals. First of all, the patients are heavily sedated and hooked up to a million tubes and monitors, so they are seldom able to talk to you. Visitors are strictly limited, and it's deadly quiet. This can be fairly isolating for someone whose previous job involved a lot of patient contact and communication.
But the biggest problem is that most of the patients are so sick that they really shouldn't be in the ICU at all. I'm talking about very, very sick people, typically elderly, with multiple comorbid conditions (metastatic cancer, heart failure, diabetes, sepsis ...). They end up dying in the ICU hooked up to IVs and telemetry, rather than in a more humane environment surrounded by their families, because they never left instructions about end-of-life care (or those instructions were ignored by their relatives). This issue is discussed in a recent article about dying by Atul Gawande:

Everyone's different, of course, but I would personally find working in the ICU to be very difficult and draining.
