What is a vasovagal reaction?
Vasovagal response is a complex brain signal that extends blood vessels in the feet, slows down heart rate and very often causes fainting, which is also called vasovagal syncope. This signal begins with some external stimulus, such as injury, blood vision or injection. People in the middle of the episode have similar symptoms to paleness, other sweating and fainting. Some techniques used to control episodes can help reduce fainting. In addition, there are options for people who often experience this problem. When the brain is activated, it signals large veins in the feet to fully blame, resulting in blood collection in the feet at abnormal speed. Its blood discharge also causes heart rate to drop below normal. Once the process is completed, it is unusual at all for people to faint, and the vasovagal syncope is considered to be the most common cause of fainting.
types of stimuli connectedThey are very diverse with a vasovagal answer. Looking at blood is a common cause, but other triggers may be much more complicated. People who have experienced trauma may have a vasovagal reaction in any situation that reminds them of this trauma. These episodes are more common in dehydrated or recently ill individuals and smokers can experience them more often. Some people can also happen right after exercise.
It is relatively easy to recognize the symptoms of vasovagal reaction in other people. Individuals are likely to look pale, have dune skin and can sweat. Other symptoms that people who have a reaction may notice are weakness, nausea and limitation of vision or hearing.
If one seems to be quite likely to fall and keep injury. Obtaining the affected individual to lie down with his head turned to the side, can help restore part of the blood flow and prevent fainting. It is also recommended to raise your legs, for example on a chair from the position of the lyingo. Place the head between the knees while sitting is an alternative position that can be useful.
Many individuals have only a vasovagal reaction in their lives and do not need any form of treatment for it. However, some people can experience these episodes often and may require help. One way to solve this problem is psychotherapy to solve reaction to triggers or stimuli. Therapy is particularly important for those suffering from conditions such as post -traumatic stress disorder or specific phobia. This has also shown that drugs such as antidepressants and beta blockers are also useful.
In some patients, the condition should be treated with their slow heart rate known as bradycardia. In this case, doctors may consider implantation of the pacemaker. A pacemaker can help reduce bradycardia episodes to prevent fainting.
