Why does epinephrine increase heart rate?
6 doctors weighed in across 2 answers
Binding receptors: Do you mean how does it increase heart rate? The mechanism of action is quite complicated but in simple term, it binds to the beta adrenergic receptors on the heart leading to changes in calcium level and increases in the firing rate of the pacemaker cells.

It is normal: It does it naturally by direct heart stimulation.
