Global Rationale: Restful cardiac response indicates that the primary input is from the parasympathetic system. These two systems work in tandem to regulate the cardiac response. Both the sympathetic and parasympathetic systems are part of the autonomic system. If the sympathetic system was in control, the heart rate would be accelerated. The somatic system is separate from the autonomic system.
