Mobile ECG monitoring for detecting heart rhythm issues in children

Effectiveness of Mobile Electrocardiogram Monitoring for Detecting Arrhythmias in Children With Symptoms: A Randomized Clinical Trial

Not applicable Interventional Centro Medico Teknon · NCT05140343

This study is testing whether using a mobile ECG can help doctors find heart rhythm problems in children aged 5-18 who have symptoms like palpitations or fainting.

What this trial studies

This project aims to evaluate the effectiveness of mobile electrocardiogram monitoring in detecting arrhythmic events in children who experience symptoms like palpitations or syncope. The study will compare this mobile approach with traditional clinical follow-up and 24-hour Holter ECG monitoring to assess its acceptability and ability to identify significant arrhythmias. Given the challenges in diagnosing arrhythmias in children, this innovative method could provide a more accessible and efficient diagnostic tool. The study will include children aged 5-18 years, with or without structural heart disease, who exhibit symptoms suggestive of rhythm disorders.

Who should consider this trial

Good fit: Ideal candidates are children aged 5-18 years with symptoms of palpitations, syncope, or dizziness, regardless of whether they have a structural heart disease diagnosis.

Not a fit: Patients who are already diagnosed with arrhythmic events or those with medical or social factors that hinder participation may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to earlier and more accurate diagnoses of arrhythmias in children, potentially preventing serious complications.

How similar studies have performed: While mobile ECG monitoring is a growing field, this specific approach in pediatric populations is relatively novel and has not been extensively tested in similar studies.
