Summary
Recurrent syncope is more common in children with a positive tilt test compared to those with a negative test. However, syncope recurrence can occur regardless of tilt test results in pediatric patients.
Area of Science:
- Pediatric Cardiology
- Autonomic Dysfunction
Background:
- Syncope is a common clinical presentation in children.
- The tilt table test is frequently used to evaluate pediatric syncope.
Purpose of the Study:
- To assess the intermediate-term outcomes of pediatric syncope.
- To investigate the relationship between tilt test results and syncope recurrence.
Main Methods:
- Retrospective study of 45 children with syncope.
- Tilt table testing was performed.
- Follow-up data collected via chart review, questionnaires, and interviews.
Main Results:
- Recurrent syncope was significantly higher in children with a positive tilt test (13/25) versus negative tilt test (2/15).
- No significant differences in age, symptom duration, or follow-up duration were observed between groups.
- Children with positive tilt tests and recurrent syncope had more episodes prior to evaluation.
Conclusions:
- Syncope recurrence is possible after both negative and positive tilt tests in children.
- The rate of syncope recurrence is notably higher in children with positive tilt test results.
