NCT ID NCT07091916
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This completed study tested a new type of implantable defibrillator (EV ICD) in 14 Japanese patients with dangerous heart rhythms. The device is placed under the skin, outside the heart and blood vessels, to deliver a shock if a life-threatening rhythm occurs. Researchers checked if the device could safely stop induced abnormal rhythms and whether there were any major complications within two weeks of implant.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Extravascular implantable cardioverter defibrillator (EV ICD) device
What this could lead to
If successful, this device could offer a new way to protect people at risk of dangerous heart rhythms without leads inside the heart or blood vessels.
What could go wrong
This was a very small, early study in just 14 people, so results may not apply to everyone. The device is still new and long-term safety and performance are not yet fully known.
