In brief: Fast versus slow

Bradycardia & tachycardia just mean slow & fast heart rate, respectively.
Each does not necessarily indicate a problem and can be normal & appropriate. For example, sinus tachycardia is a normal response to exercise or fear. If your hr does not increase with exercise, that can be a major problem. Also, bradycardia during rest (e.g., during sleep) can be normal too, especially in an athlete.
