cardiac clearance
the cardiologist will listen you your heart, then a technician will hook you up to an EKG (lots of wires!) and you will walk on a treadmill with escalating speeds until your heart rate reaches a certain point, or as far as you can stand it!
Then you'll sit down and they watch to see how long it takes for your heart rate to return to baseline. The doc then reads all these strips and you are on your way! Not too big of a deal.
