Epicardial source model at 30 ms into the QRS (upper panel). Epicardial potential map at 30 ms into the QRS, temporal correlation map and correlation plot of 16 sampling points for every simulated electrode layout (lower panel). a–c 252 electrodes surrounding the thorax, d–f 62 surrounding the thorax, g–i 62 concentrated, j–l super-concentrated. A reduced correlation was observed in areas between two electrodes (encircled in b). The highest correlation with the epicardial source model was obtained with the super-concentrated electrode placement
