Reply to the Editor —Performance and limitations of noninvasive activation mapping

We thank Dr Rudy for his remarkable contribution to the development of noninvasive electrocardiographic (ECG) mapping and for his interest in our work.1 The term ECGi was used in reference to an epicardial potential formulation using the method of fundamental solutions, as termed in previous publications. This method is used in the commercial system we evaluated. Historical validation of ECGi was performed by studying animal hearts placed in a tank filled with conductive saline, which we believe may overestimate the accuracy of the reconstruction.
