Abstract
BACKGROUND: Stereotactic ablative radiotherapy (SAbR) is an emerging therapy for refractory ventricular tachycardia (VT). However, the current workflow is complicated, and the precision and safety in patients with significant cardiorespiratory motion and VT targets near the stomach may be suboptimal.
OBJECTIVE: We hypothesized that automated 12-lead electrocardiogram (ECG) mapping and respiratory…
