AdrenalinEpinephrine is a "fight or flight" hormone, and plays a central role in the short-term stress reaction. It is released from the adrenal glands when danger threatens or in an emergency. Such triggers may be threatening, exciting, or environmental stressor conditions such as high noise levels or bright light (see Fight-or-flight response).
An example of noise-induced trigger of epinephrine release is tinnitus. The fight-or-flight response caused by tinnitus is a contributor to physical stress seen in tinnitus-patients[4], exacerbating the case.
[edit] Actions in the body
When secreted into the bloodstream, it rapidly prepares the body for action in emergency situations. The hormone boosts the supply of oxygen and glucose to the brain and muscles, while suppressing other non-emergency bodily processes (digestion in particular).
It increases heart rate and stroke volume, dilates the pupils, and constricts arterioles in the skin and gut while dilating arterioles in skeletal muscles. It elevates the blood sugar level by increasing catalysis of glycogen to glucose in the liver, and at the same time begins the breakdown of lipids in fat cells. Like some other stress hormones, epinephrine has a suppressive effect on the immune system.[5]

Sometimes it does that for no reason ; my heart does that all the time...at least once every day. It has been doing it all my life. It is nothing to worry about.
