Why each option
Bradycardia is the clinical term for a resting heart rate below 60 beats per minute, which may be normal in trained athletes or indicate a pathological slow rhythm.
A heart rate below 60 beats per minute is the universally accepted clinical definition of bradycardia. This threshold is used in cardiology and emergency medicine to identify abnormally slow heart rhythms that may stem from physiological adaptation (as in endurance athletes) or pathological causes such as heart block or sick sinus syndrome.
A heart rate greater than 100 bpm describes tachycardia, the opposite condition from bradycardia.
A heart rate of 70-80 bpm falls within the normal adult resting range and does not represent any dysrhythmia.
A heart rate of 90-100 bpm is within or approaching the upper limit of normal and does not meet the threshold for either bradycardia or tachycardia.
