What this Trial Is About
This study compares two arms - the current standard of care catheter ablation for Ventricular Tachycardia compared to stereotactic radiotherapy to non-invasively ablate ventricular tachycardia using a novel non-invasive ECG based body surface mapping technology. This allows investigators to identify ventricular tachycardia circuits to target for subsequent radio ablation. To summarize, the current standard of care invasive catheter ablation to the non-invasive radio ablation.
