TABLE 2.
Overall characteristics of accuracy for both data sets and cardiac source models and all heart–torso models. All LE values are in millimeter. ‘TCR’ stands for the ‘true classification ratio’, which is defined as the number of correctly identified ventricles (LV or RV) as the pacing site/PVC origin over the number of all available patients.
