VASOVAGAL SYNCOPE – VVS

PCOS Lady:
Many people are experiencing wanting to faint… That feeling in time is progressing to actually passing out! Many doctors are not looking further than minor diagnosing of fatigue things… Leaving symptoms to progress extremely fast in cases!
~ 2 friends i know have passed out… Both in their early 50’s… One woman passed out at work(she declined any info)… The other a man and his story is posted in a post here… Almost Fatal Crash …. https://pcoslady.wordpress.com/category/fatigue-2/
~ He now is working with a cardiologist that is putting him on a rotating table to measure his results…
~ I watched his symptoms progress extremely fast over 4 months! He and his friend are very lucky to be alive after the crash!

What is Syncope?
~
Syncope is a medical term used to describe a temporary loss of consciousness due to the sudden decline of blood flow to the brain. Syncope is commonly called fainting or “passing out.” If an individual is about to faint, he or she will feel dizzy, lightheaded, or nauseous and their field of vision may “white out” or “black out.” The skin may be cold and clammy. The person drops to the floor as he or she loses consciousness. After fainting, an individual may be unconscious for a minute or two, but will revive and slowly return to normal. Syncope can occur in otherwise healthy people and affects all age groups, but occurs more often in the elderly.
~
There are several types of syncope. Vasovagal syncope usually has an easily identified triggering event such as emotional stress, trauma, pain, the sight of blood, or prolonged standing. Carotid sinus syncope happens because of constriction of the carotid artery in the neck and can occur after turning the head, while shaving, or when wearing a tight collar. Situational syncope happens during urination, defecation, coughing, or as a result of gastrointestinal stimulation. Syncope can also be a symptom of heart disease or abnormalities that create an uneven heart rate or rhythm that temporarily affect blood volume and its distribution in the body. Syncope isn’t normally a primary sign of a neurological disorder, but it may indicate an increased risk for neurologic disorders such as Parkinson’s disease, postural orthostatic tachycardia syndrome (POTS), diabetic neuropathy, and other types of neuropathy. Certain classes of drugs are associated with an increased risk of syncope, including diuretics, calcium antagonists, ACE inhibitors, nitrates, antipsychotics, antihistamines, levodopa, narcotics, and alcohol.

Vasovagal Reflex
~
Why do some IBS sufferers have these symptoms? The most likely explanation is the body’s own vasovagal reflex. The reflex stems from our vagus nerve, which is a nerve that travels from our brains to our colons, and contributes to a wide variety of physical functions, including swallowing, speaking, heart rate and digestion.
~
The vasovagal reflex is a sudden triggering of the vagus nerve. This may occur in response to a variety of factors, including:
~
~ Fear
~ Emotional stress
~ Gastrointestinal illness
~ Pain
~ Sight of blood
~ Standing for a long time
~ Standing up quickly
~ Trauma
~ or another one for you! (everyone is different on thresh holds)
~
The reflex results in an abrupt dropping of blood pressure and a sudden reduction in heart rate. At its worst, the reflex will result in fainting, as blood flow shifts away from the head and down into the legs. Fainting that is triggered by the vasovagal reflex is called vasovagal syncope.
~
WARNING SIGNS
~
At the appearance of warning signs such as;
~ lightheadedness
~ nausea
~ cold and clammy skin
~
Counter-pressure maneuvers that involve gripping fingers into a fist, tensing the arms, and crossing the legs or squeezing the thighs together can be used to ward off a fainting spell. If fainting spells occur often without a triggering event, syncope may be a sign of an underlying heart disease.
~
YOU may experience the scenario listed below like my male friend does every time now…
~
PASSING OUT ~ WARNING SIGNS
~
~ nausea
~ profusely sweating
~ lightheadedness
~ weak
~
AMBULANCE CALLED … (“KEY” scenario)
~
~ real low heart rate
~ real low blood pressure
~ you are deemed A-Fib by EMT people
~
HOSPITAL ER … (“KEY” scenario)
~
~ heart rate OK
~ blood pressure OK
~ no sign of being A-Fib minutes later!
~ no evidence of a problem…
~
NOTE:
This scenario happens with no trail of evidence to track… Even a heart monitor may not pick up on it! Triggers cause the episodes, but may not cause them every time!
~ YOU must keep a journal on your episodes… List the triggers, the feelings, your symptoms, the time of day, how long out, how you felt after, etc… IT all shows your caring cardiologist a pattern…

Vasovagal Syncope
~
Medical Author: Benjamin C. Wedro, MD, FAAEM
Medical Editor: Melissa Conrad Stöppler, MD
~
Vasovagal syncope is a common cause of fainting. The vagus nerve is overstimulated and causes the body’s blood vessels to dilate and the heart to slow down. This anti-adrenaline effect decreases the ability of the heart to pump blood upward to the brain against gravity. Without blood flow, the brain turns off. In Victorian England, when this happened because young ladies’ sensibilities were easily offended, this was called a swoon.
~
Fortunately, the body is able to correct this temporary problem and return normalcy to the circulatory system in a matter of seconds. Unfortunately, that time delay allows the faint to happen, and while the faint itself is not a big deal, the potential complications may be. Falling is tough as you get older, kids bounce but adults tend to break. Imagine fainting while driving a car or swimming in a lake. While the grizzled veterans of the medical community laugh at the “routine faint” and then welcome the new students into their fraternity, blacking-out is not something to be taken lightly.
~
People faint at the sight of blood. Parents faint when their kids get immunized. Older people faint in church. Many types of emotional and physical stressors can stimulate the vagus nerve to do damage. But on occasion, the cause of the faint is not vasovagal syncope but something more serious. Encouraging the person to seek medical care or calling 911 may save a life. While it may be an inconvenience or sometimes an embarrassment to a patient, being unconscious is not normal. It may be easily explained…but it’s not normal.
