This chapter briefly discusses the possibilities of evaluating the diagnostic performance of the ECG by improving the model of the source and conductor. For this purpose it defines the clinical concepts of sensitivity, specificity, and diagnostic performance. Sensitivity denotes the relative number of abnormals that are detected by the system. Specificity denotes the relative number of normals that are classified as normals. The concept of diagnostic performance is defined as the average of the sensitivity and specificity of the method.

Keywords: ECG lead system; sensitivity; specificity; diagnostic performance; volume source model; volume conductor model
