This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing a new way to treat a serious heart rhythm problem called ventricular tachycardia using a technique called stereotactic body radiation therapy (SBRT). Instead of using traditional surgery, doctors use precise radiation beams to target the part of the heart causing the dangerous rhythm. The study will follow 12 patients who haven't been helped by standard treatments to see if this approach is safe and effective.
Ventricular tachycardia is a life-threatening condition where the heart beats dangerously fast. Standard treatments like medications and catheter ablation don't work for some patients, leaving them with few options. This trial is testing whether radiation therapy could be a new hope for people who have exhausted other treatments.

You will undergo several heart imaging scans (CT and MRI) to map exactly where the problem area is in your heart. A team of heart specialists and radiation doctors will use this information to plan your treatment. On treatment day, you'll lie on a special radiation machine called a TrueBeam for about 30 minutes while focused radiation is delivered to the target area. After that, you'll have follow-up visits at 6 weeks, 12 weeks, 7.5 months, and then every 6 months for up to 2 years, where doctors will check how you're doing and download information from your heart device.
