Read our Atrial Fibrillation research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing the best way to position electrodes on your chest during electrical cardioversion — a procedure that uses a controlled electric shock to restore your heart to a normal rhythm. Researchers want to compare two different electrode placements to see which one works better at getting your heart back into rhythm on the first try.
Atrial fibrillation, an irregular heartbeat, affects millions of people worldwide and can lead to serious complications like stroke and heart failure. While electrical cardioversion is the main way doctors restore normal heart rhythm, doctors aren't certain which electrode position works best — and whether applying gentle pressure to the electrodes might improve results. This trial will help doctors treat this condition more effectively.

If you join this trial, you will receive electrical cardioversion with electrodes placed in one of two positions on your chest — either front-to-side or front-to-back. If your first shock successfully restores your heart rhythm, your participation is complete. If a second shock is needed, you may also be randomly assigned to either have gentle manual pressure applied to the electrodes or no pressure, to test whether that makes a difference.
