Optical mapping from the cut surface of a “wedge preparation” allows observation inside the heart wall, below the epicardium or endocardium. We use numerical simulations based on the bidomain model to illustrate howthe transmembrane potential is influenced by the cut surface. The distribution of transmembrane potential around a unipolar cathode
depends on the fiber angle. For intermediate angles, hyperpolarization appears on only one side of the electrode, and is large and widespread.
