Syncope (medicine) Syncope, also known as fainting, passing out and swooning, is defined as a short loss of consciousness and muscle strength, characterized by a fast onset, short duration, and spontaneous recovery.It is due to a decrease in blood flow to the entire brain usually from low blood pressure.yncope, also known as fainting, passing out and swooning, is defined as a short loss of consciousness and muscle strength, characterized by a fast onset, short duration, and spontaneous recovery.

A to Z List of Neurological Disorders The medical term for fainting is syncope. Fainting is a sudden loss of consciousness, usually temporary and typically caused by a lack of oxygen in the brain. The brain oxygen deprivation has many possible causes, including hypotension (low blood pressure).his rise in the heart rate results in hypotension (drop in blood pressure) in other parts of the body, because the brain is flooded with blood (at the expense of other parts of the body). Hyperventilation combined with hypotension may result in short-term loss of consciousness, muscle weakening, and syncope (fainting).

- What is 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. Syncope can happen if you have a sudden drop in blood pressure, a drop in heart rate, or changes in the amount of blood in areas of your body.

- Syncope refers to a sudden loss of consciousness often accompanied with collapse, more commonly known as a blackout or faint. Syncope is caused by a lack of blood or oxygen to the brain.

Fainting: Causes, Symptoms, Treatment, and Prevention Fainting (syncope) is a sudden loss of consciousness from a lack of blood flow to the brain. People who faint usually wake up quickly after collapsing. Management for this condition is simple, usually requiring little more than letting the victim recover while lying flat (supine).

The Implantable Loop Recorder: Current Uses, Future Directions Syncope, defined as the transient loss of consciousness with spontaneous recovery, is a common clinical complaint encountered in medical practice. Current estimates show that syncope accounts for 3.5% of all emergency room visits and between 1% and 6% of all hospital admissions.

Understanding Fainting -- the Basics Fainting, also called syncope (pronounced SIN-ko-pee), is a sudden, brief loss of consciousness and posture caused by decreased blood flow to the brain. Many different conditions can cause fainting.

- Syncope (fainting) is caused by a sudden decrease in blood pressure, which temporarily deprives the brain of a sufficient amount of oxygen. Syncope is only one reason for someone to pass out and lose consciousness.

What is fainting and what causes it? When a person faints, the following signs may be evident: Syncope is a mechanism used by the brain to help us survive. If brain blood and oxygen levels drop considerably the brain immediately shuts down all other non-vital parts of the body so that resources can focus primarily on vital organs.

Syncope Syncope is caused by a decrease in blood flow to the brain. When blood flow to the brain decreases, oxygen to the brain also decreases. Any of the following conditions may cause syncope: Heart conditions, such as aortic stenosis, or cardiac arrhythmia (irregular heartbeat), may cause syncope.

Overview 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. 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.

- Problems with the blood vessels of the brain may cause syncope. A rapid drop in blood pressure may cause syncope. This can happen after a body position change such as moving from a lying position to a sitting or standing position. Reflexive reaction is a nervous system response that causes syncope. It can happen when you urinate or strain hard during bowel movements.

- Heart rhythm problems — A number of disturbances in the rate and/or rhythm of the heart can cause syncope. These disturbances are called arrhythmias. The heart includes an area of specialized cells in the upper right chamber of the heart (right atrium) called the sinus node (figure 1).

- Definition Collapse, unconsciousness or syncope lasting only a few seconds and generate only rarely in death. Fainting (syncope) is a disorder of consciousness of short duration which is caused by a temporary lack of blood and oxygen to the brain.

- Syncope is due to a temporary reduction in blood flow and therefore a shortage of oxygen to the brain. This leads to lightheadedness or a black out episode, a loss of consciousness. Temporary impairment of the blood supply to the brain can be caused by heart conditions and by conditions that do not directly involve the heart:

Cough Syncope Cough Syncope. Cough syncope is a syndrome in which dizziness or syncope occurs after prolonged bouts of cough. See also the syncope page, if symptoms are not particular associated with a cough or hiccup. Normal or exaggerated response to forceful cough.

Do you know the saramuyo fruit? aka sugar apple or sweetsop fruit What does the saramuyo taste like and how to use it. Since one of the other names in English is the custard apple, the name gives a hint to the flavor of this tropical fruit. A light custard flavor can be detected. This fruit is best made into a water with the pulp or into ice cream.

Syncope (Fainting) Syncope is a symptom that can be due to several causes, ranging from benign to life-threatening conditions. Many non life-threatening factors, such as overheating, dehydration, heavy sweating, exhaustion or the pooling of blood in the legs due to sudden changes in body position, can trigger syncope.

- Vasovagal syncope (also called cardioneurogenic syncope) is a condition in which temporary loss of consciousness is caused by a neurological reflex that produces either sudden dilation of the blood vessels in the legs, or a very slow heart rate (bradycardia), or both.

- Fainting, or Syncope, is a temporary loss of consciousness and muscle tone due to blood loss to the brain. It is usually caused by hypotension, or low blood pressure. Dizzy spells and feeling like you’re going to faint or pass out can be an anxiety symptom and nothing more.

Syncope and Its Causes Two general types of heart problems can produce syncope -- heart problems that obstruct the flow of blood through the heart, and cardiac arrhythmias. An obstruction to the blood flowing through the heart can cause a drop in the amount of blood being pumped by the heart, thus robbing the brain of sufficient blood flow.

- What is Syncope? Syncope refers to a sudden loss of consciousness often accompanied with collapse, more commonly known as a blackout or faint. Syncope is caused by a lack of blood or oxygen to the brain. When this happens, the brain attempts to increase blood flow to itself by diverting blood away from the rest of the body.
