Brief Summary

Ventricular tachycardia (VT) is a malignant cardiac arrhythmia subjecting our patients to a high risk of sudden death, increased morbidity and reduced quality of life. Unfortunately, failure of treatment is common and VT recurrences remain an important concern. In these patients, stereotactic arrhythmia radiotherapy appears to be an effective and safe treatment. The mechanism of action however remains unknown and should be elucidated. The objective of this phase 2, single arm, monocenter, pre-post intervention study is to evaluate the efficacy and safety of stereotactic arrhythmia radiotherapy and obtain insights in the mechanism of action by evaluating electro-anatomical alterations of stereotactic arrhythmia radiotherapy in patients with therapy refractory ventricular tachycardia.
