Zapping the heart with radiation to stop deadly rhythms
NCT ID NCT04162171
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a noninvasive radiation treatment (SBRT) for people with ventricular tachycardia, a dangerous heart rhythm that can cause sudden death. The 12 participants have structural heart disease and have not been helped by standard treatments like drugs or catheter ablation. The goal is to see if precisely targeted radiation can reduce these abnormal heart rhythms while sparing healthy tissue.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
radiation (stereotactic body radiotherapy)
What this could lead to
If it works, this could offer a noninvasive treatment option for dangerous heart rhythms when drugs and catheter ablation have failed.
What could go wrong
This is a very small early study (12 people) with no control group, so results may not apply widely. Radiation to the heart carries risks like inflammation, lung damage, or heart failure.
