How do doctors treat syncope?
When an irregular heartbeat causes fainting, your doctor may prescribe medications such as beta-blockers or antiarrhythmics. Your doctor may also prescribe steroids (such as fludrocortisone) or salt tablets to help you control the amount of sodium and fluids in your body.
What is the difference between fainting and syncope?
Syncope (SINK-a-pee) is another word for fainting or passing out. Someone is considered to have syncope if they become unconscious and go limp, then soon recover. For most people, syncope occurs once in a great while, if ever, and is not a sign of serious illness.
Why do I faint on airplanes?
A lack of oxygen, combined with airplane cabin pressure, can make some passengers feel as though they're sitting on a cliff at 8,000 feet and can lead to an in-flight fainting spell. It's a scary situation for passengers and crew.
Why did I faint on an airplane?
“It's a vasovagal episode,” said the ER doc. “You'll be fine.” He explained a number of factors that contribute to fainting: insufficient oxygen (hypoxia) due to cabin pressure, immobility, a drop in blood pressure and possible dehydration.

What is orthostatic hypotension?
Orthostatic hypotension is the most incapacitating symptom of autonomic failure. This disorder occurs with both central autonomic neurodegenerative disorders, such as multiple system atrophy and Parkinson's disease, and peripheral autonomic disorders, such as the autonomic peripheral neuropathies and pure autonomic failure. The hallmark of both central and peripheral causes of neurogenic orthostatic hypotension is the failure to release norepinephrine appropriately upon standing. Patient education is the cornerstone of management. There are several measures that can be implemented to improve orthostatic tolerance prior to pharmacological intervention. Plasma volume expansion is essential to improve orthostatic tolerance, and fluid and sodium chloride intake should be increased. Most patients can be treated successfully with volume expansion or fludrocortisone or both in combination with a sympathomimetic agent. Desmopressin acetate and erythropoietin are useful supplementary agents in patients with more refractory symptoms. There are rare patients who will require additional agents to treat their symptoms. A small group of patients remain refractory to all therapeutic modalities.
What is the hallmark of both central and peripheral causes of neurogenic orthostatic hypotension?
The hallmark of both central and peripheral causes of neurogenic orthostatic hypotension is the failure to release norepinephrine appropriately upon standing. Patient education is the cornerstone of management.
What is the best treatment for orthostatic hypotension?
Pharmacologic options include volume expansion with fludrocortisone and sympathetic enhancement with midodrine, droxidopa, and norepinephrine reuptake inhibitors. Neurogenic supine hypertension complicates management of orthostatic hypotension and is primarily ameliorated by avoiding the supine position and sleeping with the head of the bed elevated.
What is orthostatic hypotension?
Orthostatic hypotension is defined as a sustained reduction in systolic blood pressure of at least 20 mm Hg or a reduction in diastolic blood pressure of at least 10 mm Hg, usually within the first 3 minutes of standing or head-up tilt on a tilt table.1Thu s, a diagnosis of orthostatic hypotension requires blood pressure measurements. Orthostatic hypotension is not a symptom but a sign that usually indicates volume depletion, impaired peripheral vasoconstriction, or both. When orthostatic hypotension impairs perfusion to organs above the level of the heart, most notably the brain, it causes disabling symptoms that reduce quality of life and increase morbidity and mortality.
Why does neurogenic orthostatic hypotension worsen?
Marked worsening occurs after prolonged bed rest that results in striatal and myocardial muscle atrophy. These muscle changes of physical deconditioning impair both the skeletal “muscle pump” that helps venous return to the heart during active movements and left ventricular contraction reducing cardiac output.34Symptoms are worse in the morning because of overnight pressure natriuresis causing intravascular volume depletion in the morning.
How common is orthostatic hypotension in the elderly?
In the general population, the prevalence of orthostatic hypotension increases with age , and the numbers vary according to different clinical settings.1,7,8In large epidemiologic studies, such as the Cardiovascular Health Study, the prevalence of orthostatic hypotension in patients older than 65 years of age was approximately 20%, although only 2% had symptoms.9One factor influencing the high prevalence of orthostatic hypotension in the elderly is the frequency of use of antihypertensive medications.10Vasodilators (eg, α-adrenergic blockers, calcium channel blockers, nitrates), opioids, tricyclic antidepressants, and alcohol are frequently associated with orthostatic hypotension. In elderly patients, orthostatic hypotension frequently causes or contributes to hospitalization, and it is present in 25% of patients presenting with syncope in the emergency department.11The estimated orthostatic hypotension-related hospitalization rate is 36 per 100,000 adults and can be as high as 233 per 100,000 patients older than 75 years of age, with a median length of stay of 3 days and an overall in-hospital mortality rate of 0.9%.7In inpatient series, the prevalence of orthostatic hypotension in elderly patients is as high as 60%.12,13Orthostatic hypotension increases the risk of falls, cardiovascular disease, and all-cause mortality.14-21
Why is orthostatic hypotension common in elderly?
Orthostatic hypotension is frequent in the elderly due to a variety of medical conditions, such as intravascular volume depletion, blood pooling (ie, varicose veins2), severe anemia, antihypertensive medications, and physical deconditioning; in these patients, orthostatic hypotension improves dramatically or resolves after the underlying cause is treated. In a minority of patients, orthostatic hypotension is due to reduced norepinephrine release from postganglionic sympathetic nerves, resulting in defective vasoconstriction when assuming the upright position.1This is referred to as neurogenic orthostatic hypotension3and is most frequently seen in patients with diabetes mellitus; neurodegenerative disorders caused by abnormal accumulation of α-synuclein (ie, synucleinopathies); and small fiber neuropathies caused by amyloid, autoimmune, or paraneoplastic diseases.3,4Patients with high spinal cord lesions can experience neurogenic orthostatic hypotension when sitting or when placed in an upright position for rehabilitation due to lack of baroreflex-mediated activation of spinal sympathetic neurons.5Complicating the management of neurogenic orthostatic hypotension is neurogenic supine hypertension, which occurs in approximately 50% of patients with neurogenic orthostatic hypotension.6
What medications can cause orthostatic hypotension?
These drugs include nitrates, tricyclic antidepressants, diuretics, calcium channel blockers, alpha-blockers (usually prescribed for benign prostatic hypertrophy), phosphodiesterase-5 inhibitors (eg, sildenafil for erectile dysfunction), centrally acting α2-agonists (eg, clonidine or tizanidine), and beta-blockers, as illustrated in CASE 9-1. Levodopa and dopamine agonists may also lower blood pressure, and a dose adjustment may be considered based on an individual risk-benefit assessment.10,16,18,47
Is orthostatic hypotension a pathologic lesion?
If sustained orthostatic hypotension is confirmed, it is key to establish whether the cause is a pathologic lesion in sympathetic neurons (ie, neurogenic orthostatic hypotension) or if it is secondary to other medical causes (ie, non-neurogenic orthostatic hypotension), such as anemia- or dehydration-related volume depletion, excessive venous pooling sometimes aggravated by varicose veins, or medication side effects (eg, from alpha-blockers for benign prostate hyperplasia, antihypertensive agents, diuretics, tricyclic antidepressants, opioids, benzodiazepines, and antiparkinsonian agents).
How to get rid of syncope while sleeping?
Elevating the head of your bed while sleeping. You can do this by using extra pillows or by placing risers under the legs of the head of the bed. Avoiding or changing the situations or “triggers” that cause a syncope episode. Biofeedback training to control a fast heartbeat.
How to evaluate if you have syncope?
The evaluation begins with a careful review of your medical history and a physical exam. Your doctor will ask you detailed questions about your symptoms and syncope episodes, including whether you have any symptoms before you faint and when and where the episodes happen.
What is the most common type 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.
What happens when you stand up?
When you stand up, gravity causes blood to settle in the lower part of your body, below your diaphragm. When that happens, the heart and autonomic nervous system (ANS) work to keep your blood pressure stable. Some patients with vasovagal syncope have a condition called orthostatic hypotension.
What is the condition called when the blood vessels are smaller?
Some patients with vasovagal syncope have a condition called orthostatic hypotension. This condition keeps the blood vessels from getting smaller (as they should) when the patient stands. This causes blood to collect in the legs and leads to a quick drop in blood pressure.
What is the name of the condition where you can't stand and lie down?
Postural syncope (also called postural hypotension) Postural syncope is caused by a sudden drop in blood pressure due to a quick change in position, such as from lying down to standing. Certain medications and dehydration can lead to this condition.
How common is syncope?
It affects 3% of men and 3.5% of women at some point in life. Syncope is more common as you get older and affects up to 6% of people over age 75. The condition can occur at any age and happens in people with and without other medical problems.
Diagnosis
Treatment
- The goal of treatment for orthostatic hypotension is to restore normal blood pressure. That usually involves increasing blood volume, reducing the pooling of blood in your lower legs and helping blood vessels to push blood throughout your body. Treatment often addresses the cause — dehydration or heart failure, for example — rather than the low blood pressure itself. For mild o…
Clinical Trials
- Explore Mayo Clinic studiestesting new treatments, interventions and tests as a means to prevent, detect, treat or manage this condition.
Lifestyle and Home Remedies
- Some simple steps help manage or prevent orthostatic hypotension. Your doctor may give you several suggestions, including: 1. Increase salt in your diet.This must be done carefully and only after discussing it with your doctor. Too much salt can cause your blood pressure to increase beyond a healthy level, creating new health risks. 2. Eat small me...
Preparing For Your Appointment
- No special preparations are necessary to have your blood pressure checked. But it's helpful if you wear a short-sleeved shirt or a loosefitting long-sleeved shirt that can be pushed up during your evaluation so that the blood pressure cuff can fit around your arm properly. Take your blood pressure regularly at home, and keep a log of your readings. Bring the log with you to your docto…
