It depends on the individual, but if you have a strong heart (usually athletes) a resting heart rate can be below 50 without any negative effects. But, in most individuals a heart rate of 45 can be something that might need to be treated with medications or a pacemaker.

Pulse rate < 60 beats per minute is known as bradycardia.
