Scientific title
Acronym
The HOT VVS-1 study
Study hypothesis
Added 19/11/09:
To detect possible autonomic changes due to home orthostatic training (HOT) and to assess the feasibility of a larger, placebo-controlled study of HOT in vasovagal syncope (VVS).

Drug names
Primary outcome measure
Number of syncopal episodes in each patient group, which will assess the efficacy of orthostatic training.
Secondary outcome measures
1. Time to tilt-positivity
2. Time to first spontaneous syncope or pre-syncope (where this was the symptom at presentation)
3. Number of patients experiencing syncope or pre-syncope during follow-up
4. Frequency of symptoms
In addition, autonomic function tests will assess the mechanism by which orthostatic training works and improve the understanding of the mechanism behind vasovagal syncope.
The impact of orthostatic training will be assessed using quality of life measures.
