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.

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
