How do you define syncope?
Syncope (pronounced “sin ko pea”) is the medical term for fainting or passing out. It is caused by a temporary drop in the amount of blood that flows to the brain.
What is non prodromal syncope?
Syncope caused by ventricular tachycardia typically occurs without a prodrome, although some patients may report brief palpitations, with light headedness preceding loss of consciousness.
Why is it called vasovagal syncope?
Vasovagal syncope (vay-zoh-VAY-gul SING-kuh-pee) occurs when you faint because your body overreacts to certain triggers, such as the sight of blood or extreme emotional distress. It may also be called neurocardiogenic syncope.
How is syncope diagnosed?
Diagnosing vasovagal syncope often begins with a physical examination. During the physical exam, your doctor will listen to your heart and take your blood pressure. He or she may also massage the main arteries in your neck to see if that causes you to feel faint.
What are the complications of syncope?
Complications
- Recurrent syncope has serious effects on quality of life.
- Morbidity is particularly high in the elderly and includes loss of confidence, reduced mobility, depressive illness, fear of falling, fractures and subsequent institutionalisation.
What does syncope look like?
Often syncope is preceded by a prodrome or period of presyncope that may include a constellation of symptoms including lightheadedness, feeling warm or cold, diaphoresis, palpitations, nausea/abdominal discomfort, visual blurring, pallor, or changes in hearing (Benditt, 2018).
What triggers neurocardiogenic syncope?
Neurocardiogenic syncope, also known as vasovagal neurocardiogenic syncope, is a fainting spell that occurs when the body overreacts to certain triggers, like intense emotion, the sight of blood, extreme heat, dehydration, a long period of standing or intense pain.
Can High BP cause syncope?
Our data suggest that in some individuals with chronic hypertension periodic fluctuations in blood pressure that result in sudden drops from hyper- to normotensive levels may be a cause of recurrent syncope.
Can vasovagal cause death?
Over a 24-year observation period, patients whose syncope was attributed to vasovagal or other causes had a mortality ratio of 14% and an excess death rate of 20. Neurogenic syncope had a mortality ratio of 168% and an excess death rate of 34.
What happens vasovagal syncope?
Vasovagal syncope is the most common cause of fainting. It happens when the blood vessels open too wide 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.
