Summary

This small pilot study tested whether a special oral appliance (like a mouthguard) could reduce episodes of atrial fibrillation, a common heart rhythm problem. Only 3 people participated, and the study was ended early. The device is already used for snoring and sleep apnea, but its effect on heart rhythm remains unclear.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: MyTAP oral appliance plus mouth shield (a dental device that moves the jaw forward)
What this could lead to: If it works, this could point toward a non-invasive way to help control atrial fibrillation in some patients.
What could go wrong: This was a tiny pilot study with only 3 participants and was terminated early, so results are very limited. The device is not proven to treat atrial fibrillation.
