Vasovagal fainting: Deconditioning an autonomic syndrome
(continued) Regardless of its cause, fainting results from a complex series of physiologic interactions. Wright and asso ciates l reviewed the most frequently encountered types of fainting, one of which is particularly associated with an imbalance within the autonomic nervous system.

Differentiating Between Postural Tachycardia Syndrome and Vasovagal Syncope [PDF]
* Abbreviations: HUT — : head-up tilt POTS — : postural orthostatic tachycardia syndrome VVS — : vasovagal syncope Postural orthostatic tachycardia syndrome (POTS) is a clinical entity characterized by orthostatic intolerance that includes an increase in heart rate of at least 30 bpm when one changes from a supine to an

Transfer Information Assessment in Diagnosis of Vasovagal Syncope Using Transfer Entropy
The paper presents an application of Transfer Entropy (TE) to the analysis of information transfer between biosignals (heart rate expressed as R-R intervals (RRI), blood pressure (sBP, dBP) and stroke volume (SV)) measured during head up tilt testing ...
