心脏电基质是直接测量其特性的一个挑战。光学技术与在近距离制造小电极的能力一起开启了新的可能性。在这里，我们从理论的角度来探讨这些可能性。通过精心设计的一组电极的仔细测量，似乎可以获得结构导电率，将细胞内和间隔值分开，纵向和横向分开。还可以获得静止膜阻力。
The cardiac electrical substrate is a challenge to direct measurement of its properties. Optical technology together with the capability to fabricate small electrodes at close spacings opens new possibilities. Here, those possibilities are explored from a theoretical viewpoint. It appears that with careful measurements from a well-designed set of electrodes one can obtain structural conductivities, separating intracellular from interstitial values, and longitudinal from transverse. Resting membrane resistance also can be obtained.
