Mapping and ablation of ventricular tachycardia (VT) in patients with nonischemic cardiomyopathy can be challenging. In this article, we describe the approach to VT in patients with nonischemic cardiomyopathy that we use at the University of Michigan. Imaging, especially with delayed enhanced cardiac magnetic resonance imaging, plays a central role in planning a mapping and ablation procedure. During the mapping procedure, pace‐mapping in conjunction with voltage maps focusing on areas with isolated potentials helps to identify scar areas that are critical for VT in these patients.
