What is convulsive syncope?

Convulsive syncope is characterized by small jerking after fainting with spontaneous and complete recovery. This is due to decreased blood flow to the brain resulting in a seizure-like reaction. It is estimated to occur in 12% of patients presenting with syncope.

Can a heart arrhythmia cause a seizure?

Both atrial and ventricular arrhythmias can produce transient neurologic symptoms by disrupting cerebral perfusion, but ventricular arrhythmias rarely result in seizures.

How is convulsive 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.

Is convulsive syncope a seizure?

A seizure resulting from syncope is termed convulsive syncope, and seizure activity occurs in up to 20 percent of episodes of syncope. Seizures can result from an occult cardiac etiology, and some causes, such as an episodic arrhythmia, can escape elucidation in the ED.

Is convulsive syncope serious?

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.

What triggers convulsive syncope?

Sometimes there is no classical vasovagal syncope trigger, but common triggers include: Standing for long periods of time. Heat exposure. Seeing blood. Having blood drawn.

What is cardiac seizure?

When the heart beats irregularly, there can be sudden loss of consciousness and collapse due to lack of blood flow and oxygen to the brain. Sometimes there are seizure-like movements such as convulsions or muscle twitching at the same time.

Can atrial fibrillation cause a seizure?

Despite the fact that AFib can cause syncope, it is important to consider the possibility of AFib developing secondary to an epileptic seizure in cases of AFib and transient loss of consciousness. Epileptic seizures are often associated with changes in cardiac autonomic function.

What causes cardiogenic syncope?

These causes include hypoglycemia, epilepsy and stroke. The most common cause is vasovagal syncope, which is a drop in pressure with a sudden slowing of the heart. This type of syncope is often triggered by pain or emotional shock, particularly if the individual is dehydrated or has been standing for a long period.

What is convulsive movement?

A convulsive movement is jerky and uncontrollable. A convulsive sob is the kind where your body shakes when you cry, and convulsive dance moves at a party might scare your partner away. Sometimes our bodies move in ways we can’t control — like a convulsion, which is a quick, jerky muscular contraction.

Is neurocardiogenic syncope a disability?

Fainting, or syncope, can be serious if it continues to occur. As such, it is a condition that can qualify you for disability benefits. If you suffer from syncope to the extent that you have limited ability and cannot work, then you can be eligible for social security disability benefits.

Can syncope cause brain damage?

Syncope and orthostatic intolerance increase risk of brain lesions in migraineurs and controls.

What is a convulsive?

A convulsion is an episode in which you experience rigidity and uncontrolled muscle spasms along with altered consciousness. The spasms cause jerky motions that generally last a minute or two.

Is syncope life threatening?

In most cases, syncope is not a sign of a life-threatening problem, although some people with syncope have a serious underlying medical condition. In non-elderly people, over 75 percent of cases of syncope are not associated with an underlying medical problem.

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 is the most common cause of syncope?

Vasovagal syncope (also called cardio-neurogenic syncope) Vasovagal syncope is the most common type of syncope. It is caused by a sudden drop in blood pressure, which causes a drop in blood flow to the brain. When you stand up, gravity causes blood to settle in the lower part of your body, below your diaphragm.

Can syncope trigger seizures?

Syncope is common in the general population, and its symptoms can mimic seizures, including myoclonic jerks, oral automatism, head-turning, and (rarely) urinary incontinence. Syncope may also trigger a seizure in patients who do not necessarily have epilepsy.

Can dehydration cause fainting and seizures?

If you are dehydrated, which may affect the amount of blood in your body and, thus, your blood pressure, you may be more likely to faint. Heart or blood vessel problems that interfere with blood flow to the brain.

Can a seizure happen for no reason?

Anything that interrupts the normal connections between nerve cells in the brain can cause a seizure. This includes a high fever, high or low blood sugar, alcohol or drug withdrawal, or a brain concussion. But when a person has 2 or more seizures with no known cause, this is diagnosed as epilepsy.

Why do I pass out when I poop?

But straining lowers the volume of blood returning to the heart, which decreases the amount of blood leaving it. Special pressure receptors in the blood vessels in the neck register the increased pressure from straining and trigger a slowing of the heart rate to decrease in blood pressure, leading people to faint.

What happens 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.

What is Brugada syndrome?

Brugada syndrome is a genetic disorder that can cause a dangerous irregular heartbeat. When this happens, the lower chambers of your heart (ventricles) beat fast and irregularly. This prevents blood from circulating correctly in your body.

Can cardiac conditions cause seizures?

Brain ischemia or infarction of any etiology can cause seizures. Structural cardiac disease and arrhythmias cause impaired or turbulent cardiac output. The result may be poor cerebral perfusion, either globally or in areas of vascular compromise.

What conditions cause seizures?

Causes of seizures can include:

What type of seizure is status epilepticus?

A seizure that lasts longer than 5 minutes, or having more than 1 seizure within a 5 minutes period, without returning to a normal level of consciousness between episodes is called status epilepticus. This is a medical emergency that may lead to permanent brain damage or death.

How does arrhythmia cause syncope?

Serious Cardiovascular Conditions (Cardiac Syncope) Common causes of cardiac syncope: Arrhythmia and abnormal heart rhythm: During episodes of heart arrhythmia, the heart works inefficiently and not enough oxygenated blood can circulate to the brain. There are many types of cardiac arrhythmias that may cause syncope.

What happens during cardiac syncope?

Cardiac syncope is a transient loss of consciousness due to a defect, either structural or electrical, which prevents the generation of enough cardiac output to perfuse the brain adequately.

What is the most common arrhythmia leading to syncope?

ARRHYTHMIC SYNCOPE Rhythm disturbances are among the most frequent and potentially hazardous causes of syncope and dizziness. Syncope from arrhythmia most commonly results from ventricular tachycardia, which accounts for 11% of all cases of syncope.
