Vasovagal syncope (vay-zoh-VAY-gul SING-kuh-pee) occurs when you pass out because your body overreacts to certain triggers, such as the sight of blood or extreme emotional distress. It can also be called neurocardiogenic syncope.
The vasovagal syncope trigger suddenly lowers your heart rate and blood pressure. This leads to decreased blood flow to your brain, causing you to briefly pass out. Vasovagal syncope Treatment in Hyderabad
Before you faint from vasovagal syncope, you may experience some of the following symptoms:
- Pale skin
- Tunnel vision – your field of vision becomes narrower so that you can only see what is in front of you
- Feel hot
- A cold and damp sweat
Vasovagal syncope occurs when the part of your nervous system that regulates your heart rate and blood pressure reacts to a trigger, such as: B. seeing blood fails.
Your heart rate slows down and the blood vessels in your legs widen (widen). This can cause blood to pool in your legs, which lowers your blood pressure. Together, lowering blood pressure and slowing your heart rate will quickly reduce the flow of blood to your brain and you will pass out.
Sometimes there is no trigger for classic vasovagal syncope, but common triggers are:
- Stand long
- Exposure to heat
- See blood
- Have blood drawn
- Fear of bodily harm
You may not always be able to avoid vasovagal syncope. If you feel like you are going to pass out, lie down and lift your legs up. This allows gravity to circulate blood to your brain. If you can’t lie down, sit down and put your head between your knees until you feel better. Vasovagal syncope Treatment in Hyderabad
