Clinical VT Morphology and Pace Map of VT Originating From Periaortic Region
Clinical 12-lead ventricular tachycardia (VT) morphology (A) and best pace maps (B) of the clinical VT in a patient with nonischemic cardiomyopathy and VT originating from the periaortic region. Bipolar (C) and unipolar (D) electroanatomic maps (superior view) showing site of best pace map (yellow star). The red dots are sites where ablation lesions were delivered to eliminate the clinical VT. Abbreviations as in Figure 2.
