Nerves control HR: Essentially out heart rate is a balance between the "fight vs flight" side of our nervous system and the "rest and relaxation" side. Our heart rates often speed up as a compensation just after a vasovagal (rest and relaxation side slowing your heart rate and lowering blood pressure) These nerves run back by the spine and esophagus and are tied to the stomach and GI tract.
