Neurocardiogenic Syncope/ Vasovagal Syncope (Fainting)

Syncope, or fainting, is a brief loss of
consciousness and not being able to stand
up. Neurocardiogenic syncope is related to
changes within the body’s nervous system,
blood vessels, and heart. This is also
referred to as vasovagal syncope, or the
common faint. This type of fainting is not
caused by any problem with the heart’s
structure or rhythm. While not a severe
problem, we know that this can cause
problems with normal daily life. People
who have fainting can also feel dizzy when

Actions Linked to Fainting
ξ Prolonged standing, more so in a
warm environment
ξ Changing from lying or sitting to
ξ Painful events
ξ Events that cause fear or anxiety
ξ Hair combing/grooming
ξ Urination

Before fainting, a person often will feel
dizzy, nauseous, sweaty, and notice his
vision getting dark. He will often look pale.

Fluid Therapy
The most crucial part of treatment is to
increase the body’s fluid volume.

1. We suggest that you drink
__________ ounces of water and
liquids without caffeine daily. Sport
drinks that contain added salt
(sodium) can also help the body to
increase fluid volume. Limit juices
and sport drinks to ¼ of your total
fluids per day (____ Ounces).
2. During times of exercise, you will
need to drink more fluid to make up
for the loss of fluid.
3. You will need to limit the amount of
caffeine in your diet as this causes
your body to lose fluid and can
dehydrate you.

An easy way to know whether you are
drinking enough fluid is to look at the color
of your urine. Your urine should be very
pale in color to almost colorless. Dark,
yellow urine may be a sign that you need to
drink more fluid.

1. Eating regular meals will also help
prevent symptoms and fainting
2. Avoid low salt (sodium) diets.
3. Eat small amounts of pretzels or
other salty snacks in between meals.

Activities to Prevent Fainting Episodes
1. Sit or lie down as soon as you begin
to feel dizzy, notice your vision
dimming or getting dark, or have a
cold sweat.

2. Change positions slowly. Do not
jump out of bed or stand up from
sitting too quickly.
3. Regular exercise that uses the
muscles in the legs such as walking,
running, or squatting can improve

The recommendations above often work
very well in treating this type of fainting. If
you keep having fainting spells after you
have followed the above recommendations,
the use of certain medicines can help to
control symptoms. If you have fainting
episodes during exercise, you should be
evaluated by a doctor.
