The evaluation of the estimated electrograms when the heart is paced from the LV apex. (a) The 3D potential maps throughout the ventricles. The potential maps are shown on different horizontal levels from base to apex (each column), and in time sequence. The time instant after pacing corresponding to each column is indicated on the lead II ECG waveform. (b) The extracted endocardial potential map at the 46th ms after pacing and the locations of selected 10 sites on the endocardial surface. (c) The comparison of the reconstructed electrograms between the NCM system and the 3DCEI approach at 10 endocardial sites. The locations of the 10 sites are indicated in panel (b).
