Key result
In a modeling study, changes in interelectrode distance had the largest effect on the simulated electrocardiograph of an ectopic beat, while other implant dimension parameters had minor effects.

Computational modeling indicates that interelectrode distance is the primary implant dimension affecting the measured ECG during an ectopic beat.
Modeling offers effective means of studying the effects of implant dimensions on the measured electrocardiograph (ECG) prior to any in vivo tests, and thus provides the designer with valuable information. Finite difference (FDM) and lead field approaches combined with cardiac activation models offer straightforward and effective methods for analyzing different ECG measurement configurations. In the present study such methods are applied in studying the effects of implant dimensions on the simulated ECG which describes an ectopic beat originating from the apex. The results indicated that the change in interelectrode distance has the largest effects on the ECG. Other parameters related implant dimensions have minor effect on the ECG.

Väisänen et al. (2007) studied this question. Implant dimensions (interelectrode distance) was evaluated on Simulated ECG changes. In a modeling study, changes in interelectrode distance had the largest effect on the simulated electrocardiograph of an ectopic beat, while other implant dimension parameters had minor effects.
