I've been looking around to see if I can find anything to support the old guidelines that anyone exercising must not exceed their prescribed maximum heart rate of 220 minus their age.
Now that I've been doing intervals on a bike that has a built-in HR monitor, I've noticed I'll go a bit higher than my so-called maximum, and I'm not dead yet.
Is this something to be concerned about? Is this a medically tested guideline or is it just a so-called "fact" that gets circulated?

The formula is based on large populations and it's only a beginning guideline. If you improve your work capacity, you'll improve your heart rate max. Monitors are interesting to use, but measure your numbers relative to yourself. You're obviously more fit than the average joe (thank goodness!).
i was curious about this too. a few months ago i was doing intervals at the gym on the eliptical and i got my heart rate up over 200 and the machine turned off. once my heart rate got back down it started back up. but i thought it was odd then i wondered if i was doing more harm than good by getting my heart going like that.

You should write a note to National Trial Lawyer's Association and the equipment manufacturer's insurance company thanking them for thinking about your well being.

I can't believe I have something substantive to add after Lisa has already replied to a thread.
The determination of your max HR is primarily genetic. You can work very close to or at it when you are in good shape. All other things being equal, someone with a smaller heart muscle will have a higher possible max HR (smaller = less capacity = more beats to get the volume of blood out) and, usually, a higher resting HR. A person with a huge heart muscle will have more chamber capacity, more volume per stroke, and a lower max (no need). They also can have some low resting HR.
Take 2 trained individuals the same age: me and my friend Beth. She has a resting HR of 39 when she is in good shape. My RHR never goes below 56 even when I am in the best shape. On the other hand, she has tested her max HR to be close to 170, whereas mine is 204. We're both in great cardiovascular shape, we can just infer she has a larger heart muscle (or, more technically accurate, larger volume per heart stroke) than I do. She'll never get her max HR up to where I can get mine and I'll never get my RHR down to where she gets it.
The freaks of the cardiovascular world, guys like Lance Armstrong, are blessed with a great low RHR, a huge max HR, and a high anaerobic threshhold and VO2max. But they are few and far between.
The formula (which I'm hearing is being revised to be 230-age for trained adults) is a rough guideline that won't fit everyone. Since you are already above that, you can guess it doesn't fit you.

how do you find out the vo2 max? my resting used to be around 42 but i stopped doing interval training and now its around 52-56 bpm and i can get my max up to over 200bpm on the eliptical but the machine shuts off so i stopped doing that bc i figured i was doing something wrong. but when i exercise my comfortable HR is around 170-180. i am not usually breathing very hard but apparently my heart is pounding away. i thought that was bad and i keep expecting my hr to go down while i am exercising. like i get used to the energy output and become more efficient so when i run or bike or swim i can do the same amount of effort and not have my heart work as hard. so in case you haven't guessed i am clueless about this whole thing.

Max Heart Rate = 220 - age?
