Extractions: When you have syncope (loss of consciousness), your doctors main concern should be to determine whether you are at high risk for sudden death. Most syncope is benign in nature, but when it is caused by a cardiac problem, sudden death is a real possibility. In Syncope, Part I we reviewed the cardiac conditions that cause syncope, and discussed your doctors first obligation to rule out these conditions. Fortunately, most syncope is not cardiac in nature, and thus is not life-threatening. In this article, we will review the non-cardiac causes of syncope, then outline what you should expect from your doctor when you or a loved one have had a syncopal episode.

Presyncope may last for seconds or minutes. This prodromal phase may be absent in older individuals.

Extractions: www. Syncope .co.uk Home Back Next Pacemaker ... Useful Links Syncope is transient loss of consciousness causing collapse with spontaneous recovery. The underlying mechanism is transient global cerebral hypoperfusion. A sudden cessation of cerebral blood flow for 6-8 seconds is sufficient to cause complete loss of consciousness. Global cerebral hypoperfusion may be caused by a drop in blood pressure, change in the heart rhythm, or failure of cardiac output to keep up with circulatory demands. The investigation and management of syncope is now a specialist area in its own right with Syncope Clinics becoming more common. This is the commonest cause of syncope in all age groups. It occurs most frequently in young adults. It rarely presents for the first time in older people. Attacks are precipitated by recognised triggers such as fear, severe pain, sight of blood etc., and are associated with prodromal (warning) nausea, sweating, and pallor. Injury is unusual. More than 70% of syncopal spells in children are due to reflex responses. Examples include Benign Vasovagal Syncope (simple faints) and Reflex Anoxic Seizures - probably better described as Reflex Asystolic Syncope. Both of these conditions are benign, but can be very upsetting for both the child and the parents. Careful history taking is the key to diagnosis.

Syncope Contributor: Lewis A. Lipsitz (Fainting) A sudden, transient loss of consciousness characterized by unresponsiveness and loss of postural control. Etiology Many disorders can cause syncope ( see Table 18-1 ). Often a cause is neither immediately obvious nor ultimately discovered. Although syncope per se does not increase the risk of death in the elderly, it is associated with physical disability and subsequent functional decline. Abrupt reduction in cardiac output can cause syncope. This reduction may be caused by a number of cardiac disorders, most of which are more common in elderly than in younger patients. Myocardial infarction accounts for 2 to 6% of syncope among elderly patients; however, unless syncope is accompanied by other cardiac symptoms and ECG changes, myocardial infarction is unlikely. Transient ischemia and arrhythmias are other possibilities. Orthostatic hypotension is usually asymptomatic, but it can cause syncope. Among institutionalized elderly persons, orthostatic hypotension causes 6% of syncopal episodes. Orthostatic hypotension has many causes, (

Extractions: Syncope is a temporary suspension of consciousness due to generalized cerebral ischemia - a reduction in the blood supply to the brain. Syncope is a very common problem that results in approximately six percent of all hospital admissions. Neurally Mediated / Neurocardiogenic Syncope The medical term for fainting is syncope. It comes from the Greek term "syncopa", meaning "to cut short". Syncope can occur due to many reasons, and figuring out the exact cause can be difficult. Over the last several years we have learned a lot about one particular cause of fainting: The disorder now known as neurocardiogenic syncope. Neurocardiogenic syncope is also known as vasovagal syncope or neurally mediated syncope. It describes a transient failure of the brain to adequately regulate the body's blood pressure and heart rate. The exact reasons why this occurs are still unclear, but a basic understanding is evolving. The blood pressure control centers are located in the posterior parts of the brain (the brainstem or medulla). Every time a person stands, gravity pulls blood toward the lower extremities. The brain senses this change and compensates by increasing the heart rate and tightening (constricting) the blood vessels of the legs, forcing blood back upward to the brain. These centers in the brainstem (the autonomic centers), then work as a sort of thermostat to regulate blood pressure. In neurocardiogenic syncope, the system periodically breaks down allowing the blood pressure to fall too low, causing the brain to lose its blood supply resulting in loss of consciousness (fainting).

Extractions: Definition . Differentiate between near syncope and vertigo because the differential diagnosis is different. See Chapter 9 for work-up and differential of vertigo. Syncope is a sudden, brief loss of consciousness (LOC) and, strictly speaking, is related to abrupt cerebral hypoperfusion. Only two CNS lesions can cause syncope: bilateral cortical dysfunction (e.g., from hypoperfusion, etc.) or reticular activating system injury. Near syncope is a sense of impending LOC or weakness, occurs more frequently, and provides valuable diagnostic clues, since the patient usually has better recollection of the event. Frequency of causes . 55% vasovagal, 10% cardiac, 10% neurologic, 5% metabolic or drug-induced, 5% "other," and 10% undiagnosed causes.

Extractions: Research ... Patient Information Introduction Syncope is a sudden and transient loss of consciousness and postural tone, usually described as fainting or passing out. It is a common problem, accounting for 3% of emergency room visits. A history of an isolated episode of syncope will be found in as many as 25% of healthy young adults, especially in settings that precipitate fear, disgust or anxiety, and if not repeated does not warrant further work-up. Repeated episodes, however, may be caused by a wide variety of medical problems, and require diagnosis and treatment. It is important to distinguish syncope from dizziness , which generally refers to an alteration in balance, vision, or perception of the environment, without the loss of consciousness. Causes of syncope can be differentiated into two major classifications, cardiac and noncardiac . Examples of cardiac syncope are heart rhythm disturbances or abnormalities in the structure of the heart. Table 1 presents a useful classification of noncardiac syncope Table 1.

About one-third of us will faint at least once during our lifetime. A single fainting spell usually is not serious. It may be explained by factors such as stress, grief, overheating, dehydration, exhaustion or illness. If you faint suddenly and without explanation, however, contact your physician.

Heart Murmur Syncope Daisy was adopted about five months ago at which time the new owners knew she had been previously diagnosed with a heart murmur. A couple months ago, Daisy had an episode in which the owner described as beginning with a choking-like action followed by Daisy falling into lateral recumbency. Daisy remained unconscious for about one minute without movement or defecation/urination. After regaining consciousness, it took Daisy about a day to fully recover to her normal attitude. A second episode occurred last week while Daisy was going down some stairs. The owner was following behind and tried to help her get off the stairs at which time her front legs buckled under her and she remained unconscious for less than one minute. After this episode, she seemed to perk up immediately after the episode and seemed unaffected. During this episode, Daisy's tongue went white, her body was cold, and she urinated. Daisy is fairly active and climbs a long set of stairs to the owner's work everyday without evidence of tiring. She is fed once a day.
