Serotonin and vasovagal syncope
Clinical Autonomic ResearchThe goal of this manuscript was to review the biological and clinical evidence that serotonin neurotransmission might play an important role in the physiology and treatment of vasovagal syncope.The authors reviewed PubMed and handsearches of secondary sources for papers related to the Bezold-Jarisch reflex and serotonin, the plausible involvement of ...

Vasovagal syncope with asystole
JAAPAABSTRACT Although vasovagal episodes are a common cause of syncope, vasovagal syncope can be cardioinhibitory in nature, resulting in a severe heart block or asystole. This case report focuses on a young man with a history of seizures and frequent syncopal episodes who required an extensive clinical workup and treatment for cardioinhibitory ...

Prevalence of Fibromyalgia in Vasovagal Syncope
Journal of Clinical Rheumatology, 2013Vasovagal syncope is an acute manifestation of autonomic nervous system dysfunction. This type of syncope is often associated with other dysautonomic expressions such as migraine, gastroparesis, or postural tachycardia syndrome. Autonomic nervous system dysfunction has been proposed as a key element in the pathogenesis of fibromyalgia.The objectives of

Treatment of Vasovagal Syncope: An Update
Current Treatment Options in Cardiovascular Medicine, 2010Vasovagal syncope (VVS) remains the most common cause of syncope and transient loss of consciousness in all age groups. The treatment of VVS focuses on measures that interrupt or prevent its pathophysiologic mechanism, as well as on avoidance of triggers.

Vasovagal syncope and Darwinian fitness
Clinical Autonomic Research, 2005Vasovagal syncope, although often seen as a disease, is the result of a neurophysiological reflex which can be induced in most healthy people after a 30 % reduction in blood volume either by venous pooling or by hemorrhage. Studies in mammals showed that the activation of certain brainstem nuclei including the caudal midline medulla is responsible for ...

Cardiology Clinics, 2013
This review deals with recent changes in understanding of physiologic mechanisms involved in vasovagal syncope. The approach is not comprehensive but attempts to integrate new findings with older studies. The major clinical presentations of the condition and recognized triggers are discussed first, followed by a summary of how new laboratory methods ...
