• occurs
  • A cerebrovascular syncope occurs when there is a problem with the blood vessels bringing blood to the brain, most often as a result of cerebrovascular disease (e.g., stroke ). (everything2.com)
  • As this is not generally known when the syncope occurs, ths categorization process doesn't have much pragmatic use, at least urgently. (dizziness-and-balance.com)
  • Heat syncope occurs in a warm environment when blood pressure is lowered as the body dilates (widens) arterioles (small blood vessels) in the skin to radiate heat. (wikipedia.org)
  • The autonomic nervous system's physiological state (see below) leading to loss of consciousness may persist for several minutes, so If sufferers try to sit or stand when they wake up, they may pass out again The person may be nauseated, pale, and sweaty for several minutes or hours Reflex syncope occurs in response to a trigger due to dysfunction of the heart rate and blood pressure regulating mechanism. (wikipedia.org)
  • Micturition Syncope
  • There is no specific treatment for micturition syncope. (wikipedia.org)
  • General advice to men with micturition syncope includes: to sit while urinating to sit on the edge of the bed for a while before getting up and going to the toilet to avoid urinating while sleepy to urinate before sleep to stop urination, cross the legs, and flex them immediately upon feeling faintness Padevit C. (wikipedia.org)
  • Typical triggers include: Prolonged standing Emotional stress Pain The sight of blood Time varying magnetic field (i.e. transcranial magnetic stimulation) After or during urination (micturition syncope) Straining, such as to have a bowel movement Coughing Swallowing Lifting a heavy weight Pressing upon a certain spot in the neck.

  • Cardiac
  • What is cardiac syncope? (heart.org)
  • People suspected of having cardiac syncope but who don't have serious medical conditions may be managed as outpatients. (heart.org)
  • This observational study was designed to identify the predictive factors for pacemaker implantation in a population of patients receiving an implantable loop recorder for unexplained syncope with negative cardiac and neurologic workup. (medpagetoday.com)
  • In roughly 30% of syncope patients, clinicians cannot determine the etiology of the condition -- and this is despite extensive neurological and cardiac work-ups. (medpagetoday.com)
  • Symptoms
  • Patients with arrhythmic syncope have a "more rapid onset of cerebral hypoperfusion with sudden loss of postural tone and abrupt falls [without symptoms], which predisposed them to suffer trauma from an episode. (medpagetoday.com)
  • If the patient developed symptoms while engaging in physical activity and high temperatures it will then be a true case of heat syncope. (wikipedia.org)
  • If a person starts to experience over heating, and symptoms of heat syncope, they should move or be moved to a shaded or cool area. (wikipedia.org)
  • concussion
  • Syncope may be caused by a variety of mechanisms, but isn't caused by head injury , which is considered a concussion . (rxlist.com)
  • frogs
  • Syncope is a genus of microhylid frogs. (wikipedia.org)
  • Syncope bassleri are relatively small frogs: males measure about 15-20 mm (0.59-0.79 in) and females about 21-26 mm (0.83-1.02 in) in snout-vent length. (wikipedia.org)
  • bradycardia
  • However, several serious heart conditions, such as bradycardia , tachycardia or blood flow obstruction, can also cause syncope. (heart.org)
  • An advanced age, a history of trauma secondary to syncope, and the detection of periods of asymptomatic bradycardia during conventional ECG monitoring were independent predictive factors for bradyarrhythmias requiring pacemaker implantation. (medpagetoday.com)
  • diagnosis
  • Those with bradyarrhythmia related to syncope had a significantly shorter time to diagnosis compared with the others (median 5 months, range 0 to 14 versus 13 months, range 0 to 28. (medpagetoday.com)
  • The diagnosis of heat syncope is done during a physical examination. (wikipedia.org)
  • sudden
  • 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. (heart.org)
  • patients
  • Syncope is usually short in duration (20-30 seconds) and in the majority of cases, patients rarely seek medical attention. (oncologynurseadvisor.com)
  • However, despite its relative frequency, many studies have suggested that up to 40% of patients admitted with syncope will be discharged without a clear and conclusive etiology of their syncopal event. (oncologynurseadvisor.com)
  • The 55 patients from two Italian centers in this study went through those intensive work-ups (including about 90% who had invasive electrophysiology studies) and came out with no known cause of the syncope. (medpagetoday.com)
  • That the mechanism for syncope couldn't be determined with the battery of expensive tests confirms the "relative uselessness of these tests in the evaluation of patients with unexplained syncope," Palmisano and colleagues wrote. (medpagetoday.com)
  • In particular, they said, the fact that invasive electrophysiology studies came up empty "should discourage the routine use of this expensive and invasive test in the patients with unexplained syncope, even when an arrhythmic aetiology is suspected. (medpagetoday.com)
  • This finding emphasizes the need to adopt more intensive monitoring systems of arrhythmic events in patients receiving an ILR for suspected arrhythmic syncope," they wrote in conclusion. (medpagetoday.com)
  • Patients, as in this case, might present initially to the ED, and laughter should be considered among the numerous differentials for syncope. (wikipedia.org)
  • benign
  • Perhaps the most important factor to be established when evaluating a patient with syncope is whether the likely cause is benign or if it may be graver, and requires immediate clinical attention. (oncologynurseadvisor.com)
  • Most times, syncope is a relatively benign situation. (rxlist.com)
  • rhythms
  • ECG is widely available and inexpensive and can provide information about the potential and specific cause of syncope (for example, abnormal heart rhythms). (heart.org)
  • common
  • Syncope is common, but adults over age 80 are at greater risk of hospitalization and death. (heart.org)
  • Syncope hudsoni (common name: Hudson's humming frog) is a species of frog in the Microhylidae family. (wikipedia.org)
  • rule
  • Old Norse himnar "heavens" A syncope rule has been identified in Tonkawa, an extinct American Indian language in which the second vowel of a word was deleted unless it was adjacent to a consonant cluster or a final consonant. (wikipedia.org)
  • blood pressure
  • Anyone with syncope should receive an initial evaluation, including detailed physical and history examinations and measurement of blood pressure and heart rate, by a physician. (heart.org)
  • This definition does not require a fall in systemic blood pressure -- one might envision instead syncope due to choking and pressure on both carotids. (dizziness-and-balance.com)
  • If the patient is experiencing heat syncope the blood pressure will be low, and the pulse will be elevated. (wikipedia.org)
  • species
  • Syncope bassleri is an abundant and widespread species in suitable habitats. (wikipedia.org)
  • Syncope jimi is a species of frog in the Microhylidae family.It is endemic to Brazil and known from Humaitá, Amazonas, its type locality in Amazonas and from the Pará state. (wikipedia.org)

  • Syncope carvalhoi is a species of frog in the Microhylidae family. (wikipedia.org)
  • heart
  • As a preview of the 'take home' messages, the very definition of 'syncope' and variants is poorly thought through, the syncope literature is wildly variable, there is an overemphasis on heart conditions, and 'sorting' is the huge problem with syncope. (dizziness-and-balance.com)
  • cardioinhibitory syncope' is syncope mediated by slowing of the heart, or reduced contraction of the heart. (dizziness-and-balance.com)
  • Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the heart and dehydration. (wikipedia.org)
