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.
Atrial fibrillation is a common heart rhythm problem that can lead to serious complications like stroke and heart failure. This trial is testing whether the position of electrodes used during electrical cardioversion—a procedure that delivers a controlled shock to restore normal heart rhythm—affects how successful the treatment is. The study will compare two different electrode placements on the chest to see which works better.
Doctors know that electrical cardioversion is safe and effective for treating atrial fibrillation, but they're not certain about the best way to position the electrodes on the chest. Early research suggests that where the electrodes are placed, and whether gentle pressure is applied, may improve success rates. This trial will test that idea rigorously so doctors can give patients the best chance of restoring normal heart rhythm on the first try.

When you arrive for your scheduled electrical cardioversion procedure, you will be randomly assigned to have electrodes placed in one of two positions on your chest. If the first shock successfully restores your normal heart rhythm, your participation is complete. If a second shock is needed, you will be randomly assigned to receive either gentle manual pressure on the electrodes or no pressure during that second attempt. The study tracks whether the procedure works and compares outcomes between the different electrode positions.
