Reflex Syncope (Neurally Mediated Syncope, Vasovagal Syncope, Vasodepressor Syncope, the Common Faint) Reflex syncope is the result of a reflex response to some trigger, in which the heart slows or blood vessels dilate (widen).
Syncope is classified as neurally mediated, cardiac, and orthostatic hypotension. Neurally mediated syncope is the most common type and has a benign course, whereas cardiac syncope is associated with increased morbidity and mortality.
Common causes of syncope include:
Vasovagal syncope has three distinct phases: a prodrome, loss of consciousness, and a postsyncopal phase. A precipitating event or situation (e.g., emotional stress, trauma, pain, sight of blood, prolonged standing) usually is identifiable.
A drug called fludrocortisone acetate that's normally used to treat low blood pressure may be helpful in preventing vasovagal syncope. Selective serotonin reuptake inhibitors also may be used. Therapies. Your doctor may recommend ways to decrease the pooling of blood in your legs.
Cardiac pacing, implantable cardioverter‐defibrillators, and catheter ablation are the usual treatments of syncope caused by cardiac arrhythmias, depending on the mechanism of 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.
Position the patient: The patient should be in a supine position with the feet elevated slightly. Assess circulation, airway and breathing: Monitor the pulse and blood pressure. Assess the patient's breathing and airway patency and adjust the head and jaw position accordingly.
' If you have fainted, you should see a physician or visit an emergency room right away to identify the cause of your fainting and to ensure you do not have a serious underlying condition. Generally, fainting indicates a drop in blood pressure resulting in too little blood (and, hence, oxygen) reaching your brain.
Who should be admitted after an episode of syncope of unclear cause? Patients with syncope who are determined to be at risk for significant dysrhythmia or sudden death should be admitted to an inpatient unit, observation unit, or other monitored area.
It is recommended that you lay the person down and elevate their feet. Most people will recover quickly after fainting once they lay down because more blood can flow to your brain. It also helps to loosen any constrictive clothing.
You probably don't need to go to your doctor if you have only fainted one time and you are otherwise in good health. Fainting is common and usually not serious. However, if you have serious health problems or are on multiple medications, you probably should see your doctor.
Fainting happens when you lose consciousness for a short amount of time because your brain isn't getting enough oxygen. The medical term for fainting is syncope, but it's more commonly known as “passing out.” A fainting spell generally lasts from a few seconds to a few minutes.
You will get more blood to your brain by doing this rather than leaning over and putting your head between your knees. 2. If fainting seemed to happen after not having enough to eat or drink, once your child is fully awake have them drink some fruit juice (orange, grape, or apple juice are fine).
In severe cases, low blood pressure can be life-threatening. A blood pressure reading lower than 90 millimeters of mercury (mm Hg) for the top number (systolic) or 60 mm Hg for the bottom number (diastolic) is generally considered low blood pressure.

Bananas. You've heard that an apple a day keeps the doctor away. But you might not know that a banana a day keeps high blood pressure at bay. This fruit is packed full of potassium -- an important blood pressure-lowering mineral.
The lower number indicates how much pressure the blood is exerting against artery walls while the heart is at rest between beats. When an individual is approaching death, the systolic blood pressure will typically drop below 95mm Hg.
What happens when someone dies? In time, the heart stops and they stop breathing. Within a few minutes, their brain stops functioning entirely and their skin starts to cool. At this point, they have died.
In the last hours before dying a person may become very alert or active. This may be followed by a time of being unresponsive. You may see blotchiness and feel cooling of the arms and legs. Their eyes will often be open and not blinking.
This difficult time may be complicated by a phenomenon known as the surge before death, or terminal lucidity, which can happen days, hours, or even minutes before a person's passing. Often occurring abruptly, this period of increased energy and alertness may give families false hope that their loved ones will recover.
