Vasovagal syncopeIn adults, neurally mediated syncope means neuro-cardiogenic or vasovagal syncope. In childhood, the term has a broader meaning, but it may be helpful to discuss vasovagal syncope of the classical type, which is the best known of the syncopes [1].John B.P. Stephenson...

The reflex that causes vasovagal syncope can affect anyone and fainting spells are common. However, some people are more at risk of fainting from vasovagal syncope than others. Young Adults and Adolescents Vasovagal syncope can occur at any age but is more common in adolescents and young adults....
In this population sensitivity and specificity was markedly reduced: 0.13 (95 CI 0.050.29) and 0.70 (95 CI 0.570.80), respectively.The CSSS has a lower sensitivity and specificity in an elderly population presenting with syncope compared to previously validated data in young adults, particularly ...

The analysis of complexity in chosen measurement phases was performed with Sample Entropy. The investigation showed that the reactions of autonomic nervous system during tilt test and before syncope are similar for positive result of passive tilt test and positive result of tilt test with provocation....

Syncope secondary to abdominal pain was reproduced during HUT. Further, HUT revealed vasovagal syncope, and synchronous TCD showed decreased cerebral blood flow; the final diagnosis was VVS in all cases. Conclusions: Abdominal pain may be a precursor of VVS in adults, and our findings enrich the...
