The heart has a very important role. It pumps and pumps to keep you alive. But people usually do not recognize this importance unless they get robbed or run 50 meters to catch a bus, or when about to kiss someone special.
In these cases, our heart beats at a crazy speed, as if it's going to leave our body. But, do we have to worry about this? A heart specialist says: probably we should not. The heart is a very capable organ. It pumps the exact amount of blood that the body needs, no more no less, as this would be considered a waste of energy, says Dr. Karl Stangl, acting director Medical Department, Division of Cardiology and Angiology at the Berlin-based Charité Hospital. When you feel scared, an evolutionary response takes place in your body.
According to the German News Agency, the autonomic nervous system, which controls the involuntary functions in the body, triggers the fighting or escape response, to provide the body with an energy flow to face the anticipated danger.
The adrenal glands, located above each kidney, secrete the epinephrine hormone (also known as adrenaline), in the bloodstream. As a result, the heart beats faster, but also pumps more blood per heartbeat to the muscles and vital organs. The heartbeats maintain their acceleration, and you cannot control it.
Stangl says "the autonomic nervous system is called autonomic for a reason" noting that there is no harm if the heart pumps more blood every once in a while.
"A sound body can deal with this smoothly for a while," he explained. However, if your heartbeats' speed increases without a clear explanation, Stangl advises you to visit the hospital. In rare cases, rapid heartbeats could indicate a dangerous heart disease.
