In brief: Normal or abnormal

Could be normal if physically fit as in athletes due to high parasympathetic tone.
Abnormal sinus bradycardia could be due to degeneration of the cells in the sinus node, certain medications such as beta blockers , Diltiazem or verapamil and sinus node ischemia( insufficient blood flow).
