In the assessment of primary outcomes-free survival, patients with cardiogenic syncope and syncope from unknown origin had significantly higher rates of adverse outcomes compared with
vasovagal syncope and postural hypotension.
Steep fall in cardiac output is main determinant of hypotension during drug-free and nitroglycerine-induced orthostatic
vasovagal syncope. Heart Rhythm 2008; 5: 1695-701.
The patient's history of
vasovagal syncope was certainly indicative of increased susceptibility to reflex-mediated events, thus supporting our hypothesis.
(2002) tested this procedure by recruiting 21 participants predisposed to
vasovagal syncope, and subjecting them to a tilt table test while they performed the applied tension maneuver.

Vasovagal syncope Vasovagal syncope is the most common cause of acute brief unconsciousness.59 It is far more prevalent than anaphylaxis.
He succeeded great researches on pacemakers and
vasovagal syncope. In cardiology, when you think about dual chamber pacemakers, neurally mediated syncope, he is the first to be remembered.
Perioperative bradycardia and asystole: relationship to
vasovagal syncope and the Bezold-Jarisch reflex.
The topics include arterial blood pressure waveform analysis and its applications in assessing
vasovagal syncope, heart rate variability analysis for monitoring fetal distress and neonatal critical care, bariatric surgery and its effects on heart rate variability, heart rate variability in congestive heart failure, and heart rate variability and depression.
Vasovagal syncope is the most common form of fainting, caused by a sudden drop in blood pressure in response to triggers like scary thoughts, seeing blood or standing too long.
And now Rachel understood that the
vasovagal syncope did have significance.
Waldman and associates (17) in a prospective study of 790 blocks in 215 patients, found two dural punctures, two episodes of
vasovagal syncope, and one late superficial infection.
Low resting blood pressure, especially in rapidly growing teenagers, can predispose your patients to
vasovagal syncope. Patients with low resting blood pressure often have a lower threshold for syncope, compared with children with normal pressure.
