The method may include receiving at a computing device a plurality of ECG signals from an acquisition system. The pace site BSPM may be calculated using the plurality of ECG signals. The BSPM of interest may be compared to the pace site BSPM, by: retrieving the BSPM of interest from memory accessible by the computing device; and, calculating one or more comparison metrics for the BSPM of interest as compared to the pace site BSPM. An indication of similarity between the BSPM of interest and the pace site BSPM based on the comparison metric calculated may be displayed on a user interface in communication with the computing device.Figure 1 140_1 110_1 Patient 110_2 Acquisition System Computing 100 120 1110_N 130 140_N J '2 5" " 1 g3 ir~ ~ -A54M-Z c9 1.l to I 4 H' 0 G F F E' D' [ D V C E 8 A A F~ P OF 0 N' N M' M L' L W( T r g 9, Figure 2 1/12
