Study information

Primary study designInterventional
Study designRandomised multi-centre, active controlled, parallel group, single blinded trial
Secondary study designRandomised controlled trial
Scientific titleRandomised trial of optimal conventional therapy versus optimal conventional therapy plus counterpressure manoeuvres in patients with neurally-mediated syncope
Study acronymPC-Trial
Study objectivesIn patients with syncope and absence of significant structural heart disease, physical counter pressure manoeuvres decrease the total syncope burden compared to standardized intensive conventional therapy.
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedVasovagal syncope
InterventionPhysical counterpressure manoeuvres compared to standardised intensive conventional therapy.
Intervention typeOther
Primary outcome measure(s)

Total burden of syncope recurrence (number of syncopal spells/year/patient).

Key secondary outcome measure(s)

1. Time to first recurrence
2. Presyncope burden
3. Quality of life

Completion date09/01/2005
