When should I be concerned? I don't feel any pain or get dizzy, even in those high numbers.

Don't know that's it so much about getting concerned; but I'm not so sure you're doing aerobic activity at that point ... and you're almost certainly not in a fat burning zone. My rule of thumb with any cardio is that if I want it to be aerobic, I don't push past the point of not being able to cary on a conversation. In other words, if you're breathing hard enough that you can't cary on a conversation with the person next to you, then you're pushing too hard.
That said, the high heart rate, high intensity stuff has it's place. It all just depends on your goals. For example, when I do High Intensity Interval Training (HIIT), my heart will be racing something fierce at the peaks; but the point of that it so build up endurance and not to engage in aerobic exercise.
So that's my answer/non-answer.
