What controls heart rate? Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).

The parasympathetic nervous system (PNS) releases the hormone acetylcholine to slow the heart rate.
