can you define sinus bradycardia?

Yes: A slow heart rate in which the electrical signal for each heartbeat originates from the sinus node (where it's supposed to originate). Generally, in an adult, this means a heart rate of less than 60. But keep in mind you can have a heart rate less than 60 and still be okay. For example many good athletes, whose hearts are in great shape, have resting heart rates less than 60.

HR : Any heart rate less than 60 beats per minute.
