Double the shock, double the success? new trial tests dual cardioversion for AFib
NCT ID NCT07560644
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This clinical trial tests whether giving two electrical shocks at once (dual shock) is better than the standard single shock for restoring normal heart rhythm in people with persistent atrial fibrillation. About 177 participants will be randomly assigned to receive either a standard 200-joule shock or a dual 400-joule shock. The study will measure how many people return to normal rhythm after the first shock and track any side effects.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- electrical cardioversion (dual shock technique)
- What this could lead to
- If successful, this could provide a more effective way to restore normal heart rhythm in people with persistent atrial fibrillation, reducing the need for repeated procedures.
- What could go wrong
- This is a mid-stage trial with only 177 participants, so results may not apply to everyone. The dual shock carries a small risk of complications like skin burns or arrhythmias.
