I don't know, but I think there are some heart conditions that might give you such. As well sometimes whether or not you are dehydrated from not drinking enough fluids or are just overworked and tired can affect your HR during times you are riding your bike.
So consulting a medical professional might be a wise move.
MIght be, but I doubt it. Unless you've got a working relationship with a cardiologist who's an athlete and tuned into the kind of riding you do. Otherwise, my experience was you get lots of "Wow, your resting pulse rate is really low!" or "You ride your bike on the road? Aren't you afraid you'll get killed?" kinds of comments. You can spend a lot of money on specialists and EKGs and get nothing more than "I wouldn't worry about pulse changes of less than 10 bpm."
