Study Summary
This trial will assess whether counterpressure maneuvers (CPM) can prevent syncope in children. In stage I, participants will fill out a survey about their syncopal episode and any prodromal symptoms. In stage II, some participants will be trained in CPM and all will be followed for one year. Surveys and medical records will be used to assess syncopal and presyncopal recurrence and changes in medical diagnosis.

A total of 300 participants need to be admitted across 1 healthcare centre." - Anonymous Online Contributor
What does the research team hope to accomplish through this investigation?
"This study aims to evaluate the number of patients with syncopal recurrence over a 12 month period. Secondary objectives are to define predictive factors for syncope secondary to other causes, determine diagnosis in pediatric patients who may experience exercise-related syncope, and document typical prodromal symptoms that link different types of syncope in the pediatric population after 1 year follow up." - Anonymous Online Contributor
Who has the requisite qualifications to join this medical study?
"Candidates that would like to take part in this medical trial must possess syncope, be younger than 18 years old and older than 6 years. The maximum amount of participants allowed is 300 individuals." - Anonymous Online Contributor
How many participants have been recruited for this experiment?
"Affirmative. As per the data posted on clinicaltrials.gov, this trial currently requires participants and was first listed on September 3rd 2022. The most recent changes were made November 10th 2022 and 300 people are needed from a single site." - Anonymous Online Contributor
