Stereotactic radiotherapy, successfully and effectively used in the treatment of solid tumors, has recently emerged as a new approach in the management of heart rhythm disorders resistant to medication and ablation therapy. Particularly in cases where the area originating the arrhythmia cannot be reached by ablation, stereotactic radiotherapy can provide treatment for such tachycardias through highly precise irradiation using computer-assisted 3D devices.

This treatment requires a comprehensive preparation process carried out through close collaboration between radiation oncologists and cardiologists. The process typically begins with detailed mapping and localization of the source region for tachycardias, which often originate from scar tissue developed after a heart attack. The boundaries of this region are then confirmed using advanced radiological imaging methods such as cardiac MRI and computed tomography, and carefully marked by radiation oncologists.

Following preparation, the treatment is delivered by sending highly precise, pinpoint radiation to the identified target using computer-assisted devices with 3D irradiation capabilities.
