What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing

Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This completed study looked at how 1,400 children with supraventricular tachycardia (a fast heart rhythm) were treated in France. Researchers compared the use of antiarrhythmic drugs and catheter ablation to see which worked better and had fewer side effects. The goal is to help doctors make more informed treatment choices for children of different ages.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors choose the best treatment for children with rapid heartbeats, reducing recurrences and side effects.
What could go wrong
This is an observational study, not a controlled trial, so it cannot prove one treatment is better. Results may not apply to all children.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who is studied

All children \<18 years old with a documented episode (ECG, Holter-ECG, wearable device, or implantable device) of sustained SVT (\>30 seconds) will be eligible. Although most children in this context do not have structural heart disease, those with congenital or structural heart disease will also be eligible. Participation will be proposed to all pediatric cardiology centers in France through the Filiale de Cardiologie Pédiatrique et Congénitale (FCPC).
