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
Running, but no longer taking on new participants.
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested a non-invasive mapping system (Cardioinsight®) to help doctors treat heart rhythm disorders. It included 492 patients who needed ablation, pacemaker implantation, or risk assessment for sudden death. The goal was to see if the mapping system improves outcomes compared to standard methods without mapping.

What this could mean

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

Active substance
Cardioinsight® mapping system (device)
What this could lead to
If successful, this could make heart rhythm procedures more precise and reduce the need for repeat treatments.
What could go wrong
This is a completed care protocol, not a randomized trial, so results may be less definitive. The device may not work for all types of arrhythmias.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

492 people

The number who actually took part.

Started

May 2015

Finished

May 2020

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

15 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Oral agreement of the patient or of the holder of parental responsibility after reading the informed consent form. * Patients with the following 3 conditions : * Ablation of drugs rebels arrhythmias. * Or implantation or programming of a pacemaker (pacemaker or defibrillator) * Or symptoms and / or cardiopathy with risk of sudden death. Exclusion Criteria: * Pregnancy and lactation. * Patients unable to give oral agreement. * Inconsistent patient's morphology with the establishment of the electrode jacket
