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

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 tested a new catheter designed to measure the heart's electrical signals in people with irregular heartbeats (atrial fibrillation, ventricular fibrillation, or junctional tachycardia). Researchers enrolled 42 adults to see if the device could better identify abnormal electrical patterns. The goal was to improve understanding of how these arrhythmias work, not to provide direct treatment.
