What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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 for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
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 Results may not be published yet.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

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.

Summary

This study looks at whether a standard 12-lead electrocardiogram (ECG) can tell if a patient is eligible for a subcutaneous defibrillator (S-ICD), a device that prevents sudden cardiac arrest. Currently, patients need a special 3-lead screening ECG, but researchers want to see if the standard ECG works just as well. They will analyze ECGs from 1,000 adults using artificial intelligence to find markers that predict success.

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 could simplify the screening process for subcutaneous defibrillators, making it faster and more accessible.
What could go wrong
This is an observational study, not a treatment trial. The results may not change current practice if the standard ECG proves unreliable.
