Comparison of the local potentials among the 4 segments of the SVC
Figure 3 shows the comparison of the local potentials among the 4 segments of the SVC. The median amplitude of the local potentials at each segment was as follows: anterior area, 0.36mV (0.20-0.76); septal area, 0.35mV (0.20-0.73); posterior area, 0.23mV (0.14-0.50); and lateral area, 0.23mV (0.12-0.50). The local potential was highest at the anterior area and lowest at the posterior and lateral areas.
