Generation of a cohort of whole-torso cardiac models for assessing the utility of a novel computed shock vector efficiency metric for ICD optimisation.

Similarly to previous studies [ 12 ], despite fairly significant changes in cardiac anatomy when representing the HCM and DCM hearts (seen in Fig. 3 ), there was no clear difference seen in DFTs between these different pathologies.

The Small patient data appears to be an outlier in this case; on the whole, there seems to be a slight trend for increases in shock vector efficiency in both HCM and DCM across all electrode configurations. 3.6 Relating η to DFTs and impedances The degree to which the metrics DFT, impedance and shock vector efficiency are related to one-another is now explicitly explored by producing correlation plots.
