Study summary

multicenter prospective randomized controlled comparison of biofeedback with tilt table testing (investigational management strategy) vs biofeedback without tilt table testing (reference management strategy) in patients with certain/highly likely vasovagal syncope

Read the detailed description

Syncope is very common and has a broad differential diagnosis. The diagnosis reflex syncope, orthostatic hypotension, POTS or psychogenic syncope rely mainly on the initial syncope evaluation that consists of history taking, physical examination (including supine and standing blood pressure measurement) and ECG (class I, Level C). Besides the initial evaluation for the diagnosis also reassurance, explanation and education with biofeedback on life style measures is an important part of standard care and treatment of these patients (class 1, level B). In the current guidelines on syncope, provocation on tilt table testing should be considered in patients with suspected reflex syncope (Class IIb, Level B). For vasovagal syncope, which is a form of reflex syncope, tilt table testing has become a widely accepted tool in the work up and treatment, however evidence for this is lacking so far. In current medical practice there is a true equipoise for the use of provocation on tilt table in these patients. A randomized controlled trial to compare the standard of care without tilt table test versus standard of care with tilt table test in patients with certain/highly likely vasovagal syncope has never been done so far.

Inclusion criteria

  • All patients >18 years of age with certain/highly likely vasovagal syncope after the guideline based syncope evaluation

Exclusion criteria

Exclusion Criteria:

  • Those aged \<18 years
  • Any patient diagnosed with another form of reflex syncope other than vasovagal syn-cope
  • for tilt table testing at the discretion of the responsible physician
  • Those with a learning disability
  • Those presenting with pre-syncope and not with complete loss of consciousness
  • Those who are unwilling to provide
  • Those already diagnosed prior to evaluation who are referred for specific treatment op-tions
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Syncope recurrence rate

    The rate of syncope recurrence

    Time frame: From enrollment to the end of the follow-up at 12 months.

  2. Time till first syncope

    Time till the first syncope after tilt-table testing

    Time frame: Enrollment to 1 year after tilt-table test

Secondary outcomes

  1. Near-syncope recurrence rate

    Amount of near-syncopal events

    Time frame: Enrollment till 1 year after tilt table testing

  2. Health Technology Assesment

    Amount of made healthcare costs

    Time frame: Enrollment till 1 year after testing

  3. Quality of life

    Quality of life using: SF-12: Short-form 12: higher scores indicate a better quality of life. Scores are transformed using standardized transformation. Mean score 50; population score mean / mean score 40 or 60 equals a 1SD deviation from the mean population score. SDF: Syncope daily function: higher scores are better daily functioning Minimal score 16, maximum score 51

    Time frame: Enrollment till 1 year after testing

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2025 (actual). Primary completion is estimated for Jun 2027, 19 months after the start.

Of 29 interventional studies with no phase under Syncope, Vasovagal, half reached primary completion within 39 months of starting (the median), counting those still running; a quarter within 15. This study's planned 19 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 11, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
