There are several nerves that regulate the heartbeat. The heartbeat starts when a signal is given off from the SA node. The main nerves in the heart are called the Purkinje Fibers.
Vagus and accelerator
sinoatrial node
The somatic nervoussystem system does not control your heartbeat. The autonomic nervous system controls your heartbeat via accelerans nerves of the sympathetic division and vagus nerves of the parasympathetic division. Depending on which signal is sent to the medulla, the accelerans release noradrenaline at the post ganglionic endings on the Sino-Atrial Node speeding up the heart beat or the vagus nerves signaling for the Sino-Atrial Node to slow the heart's pace down. The accelerans nerves are active during physical or emotional stress on the body. The vagus nerves are active due to pressure receptors in the aorta and carotid arteries sending impulses to the medulla that relay the information to the heart to slow down which is usually during resting times.
