Chronotropy

Chronotropy is the influence of heart frequency. Positive chronotropy suggest faster heart frequency (for example an increased activity if the sympathetic nervous system has a positive chronotropic effect on the heart), on the contrary a negative chronotropy indicates a slower heart frequency (increased activity of the parasympathetic nervous system causes a negative chronotropy).
