Summary
The tilt test effectively diagnoses syncope in children and adolescents, aiding in stopping further investigations and reassuring families. This non-invasive method guides treatment and allows young patients to resume activities.
Area of Science:
- Cardiology
- Pediatrics
- Clinical Investigation
Context:
- Syncope and unexplained malaises are common in children and adolescents.
- The tilt test is a valuable non-invasive diagnostic tool for this population.
- Previous research has established the utility of the tilt test in adult syncope diagnosis.
Purpose:
- To evaluate the efficacy and diagnostic value of the tilt test in pediatric patients experiencing syncope or unexplained malaises.
- To assess the test's positivity rates, response types, and correlation with symptoms in children.
- To determine the impact of the tilt test on subsequent investigations, patient reassurance, and treatment guidance.
Summary:
- The tilt test was performed on 105 children (aged 4-18) with syncope. The test was positive in 44% of cases, with symptoms reproduced in 36 children and significant blood pressure drops in 10 others.
- Positivity included cardio-inhibitory, vasodepressive, and mixed responses, often preceded by sinus tachycardia.
- Treatment with disopyramide or betablockers led to asymptomatic outcomes in most children, though the tilt test remained positive in some, indicating its diagnostic value beyond immediate symptom resolution.
Impact:
- The tilt test simplifies diagnosis, reduces the need for further investigations, and provides reassurance to children and parents.
- It facilitates the safe resumption of physical activities for pediatric patients.
- The test guides appropriate medical treatment for syncope, improving patient management and outcomes.
