Radiation Oncology/Arrythmia


 * SBRT for cardiac arrhythmias also termed stereotactic arrhythmia radioablation (STAR)
 * Stereotactic radioablation has been used to safely and effectively treat a limited number of patients with malignant arrhythmias:
 * Ventricular tachycardia (VT)
 * Atrial fibrillation (AF)
 * Unlike catheter-directed radiofrequency or cryoablation, in which tissue destruction is effected by thermal injury, radiotherapy uses gamma-rays or x-rays directed in high doses (typically 25–30 Gy) to a three-dimensional volume of target tissue
