Abstract

An imaging modality that combines electrocardiography and computed tomography identifies the origins of ventricular tachycardias (Wang et al., this issue).

ECG combines with CT imaging to produce 3D maps of electrical activity on the surface of the human heart. Multiple surface electrodes are used to generate ECG data for body surface potential mapping. High-resolution CT images provide information on the anatomy and orientation of the heart and chest wall. Electrical and imaging data are processed by the ECGI algorithm to provide a map of electrical activation.
