Causes of vasovagal syncope:
It is known as vasovagal syncope or fainting common to the most common cause that causes loss of consciousness. It is due to the existence of a stimulus that causes a stress in the affected person, which produces a stimulation of a nerve called “vagus nerve”, decreasing the heart rate and increasing the volume of the blood vessels, causing a deficiency in the arrival of blood and therefore of oxygen to the brain, whose final manifestation is fainting.
Yoram Yasur Izz: “The stimuli that produces the vasovagal syncope can be very varied and depends a lot on each person; Something that affects a person is not always going to affect anyone else”. These stimuli are usually those related to anxiety, fear or feeling threatened. The most common situations that produce vasovagal syncope’s are, for example, the presence of own blood or other blood, sudden scares or emotions, pain, going to consult with a doctor, and, in general, any situation that makes the affected person feel in a threat.
Symptoms of vasovagal syncope:
The symptoms that are felt before suffering the vasovagal syncope are characterized by being easy to identify:
In a first phase before syncope the affected person usually feels:
- A feeling of heat and sweating even if you are in a cool environment.
- Paleness of the skin
- Ringing in the ears
- Want to urinate
Then comes the second phase of syncope, prior to final fainting:
- The visual field begins to shrink, becoming dark from the periphery to the center until the vision completely dark, which usually coincides precisely with the loss of consciousness.
- Those affected are usually standing now of loss of consciousness, and therefore fall to the floor suddenly. At this point, the affected person is very likely to injure themselves depending on the force of the fall, the type of soil or if any object with which he may get injured can get in the way of their fall.
- The person who has suffered a vasovagal syncope usually gets the consciousness being very disoriented and having little memories of what has happened. Rarely, the absence of oxygen in the brain can produce brief seizures.
