About this study
Official title: Comparing Phenotypic and Autonomic Physiologic Determinants of Neurocardiogenic Syncope
This is a prospective observational pilot study of suitability of autonomic monitoring via the VU-AMS device for prediction of neurocardiogenic syncope (NCS) in children referred to cardiopulmonary exercise testing (CPET) for a diagnosis of syncope. The study population is children referred for CPET to evaluate for neurocardiogenic syncope. The purpose is to describe autonomic function during rest and exercise and determine the positive predictive value of autonomic function measurements against the gold standard for diagnosis of neurocardiogenic syncope, the CPET. Children presenting for CPET with chest pain or who are status post orthotopic heart transplantation will serve as positive and negative controls respectively.

Questions about this trial
What is this clinical trial studying?
An observational study of Syncope and Chest Pain, run by Children's Hospital Medical Center, Cincinnati at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Autonomic data respiratory sinus arrhythmia among patients with chest pain (time frame: Data collected throughout cardiopulmonary exercise testing. Up to 90 minutes.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05907018, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jan 2025.
