What triggers neurocardiogenic syncope?
What triggers neurocardiogenic syncope?
Neurocardiogenic syncope is caused by an abnormal or exaggerated autonomic response to various stimuli, of which the most common are standing and emotion. The mechanism is poorly understood but involves reflex mediated changes in heart rate or vascular tone, caused by activation of cardiac C fibres.
What causes vasovagal shock?
Vasovagal syncope is the most common cause of fainting. It happens when the blood vessels open too wide and/or the heartbeat slows, causing a temporary lack of blood flow to the brain. It’s generally not a dangerous condition. To prevent fainting, stay out of hot places and don’t stand for long periods.
Can you drive if diagnosed with vasovagal syncope?
Loss of consciousness/ loss of or altered awareness likely to be unexplained syncope but with a high probability of reflex vasovagal syncope. No driving restrictions.
How do you feel after vasovagal syncope?
After an episode of vasovagal syncope, many people will feel terrible for a few hours or even for the next few days, or even longer. During this “postdromal” period they commonly experience extreme fatigue, nausea, dizziness, and loss of appetite.
What happens when you have a vasovagal syncope episode?
The vasovagal syncope trigger causes your heart rate and blood pressure to drop suddenly. That leads to reduced blood flow to your brain, causing you to briefly lose consciousness. Vasovagal syncope is usually harmless and requires no treatment. But it’s possible that you may injure yourself during a vasovagal syncope episode.
How are pacemakers used to treat vasovagal syncope?
Very rarely, inserting an electrical pacemaker to regulate the heartbeat may help some people with vasovagal syncope who haven’t been helped by other treatments. Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this disease.
Can a syncope occur without any identifiable trigger?
Their syncope may occur without any identifiable trigger, and without any warning symptoms. Making the correct diagnosis in these cases can present a real challenge to the doctor. In general, vasovagal syncope is not itself life-threatening, but injuries that result from falling may be.
