    Abstract
    Four electrode techniques have long been used to determine conductivity parameters in cardiac tissue. This paper in troduces a mathematical model and solution technique to theoretically analyse electrode configurations, specifically allowing for plunge electrodes. In particular, the focus is on using four electrode configurations to determine fibre rota tion in cardiac tissue. Two configurations are analysed, the first with the four electrodes collinear and the second with one electrode removed from the line of the other three. It is found that the second electrode configuration can yield a value for the fibre rotation under ...

    Four electrode techniques have long been used to determine conductivity parameters in cardiac tissue. This paper in troduces a mathematical model and solution technique to theoretically analyse electrode configurations, specifically allowing for plunge electrodes. In particular, the focus is on using four electrode configurations to determine fibre rota tion in cardiac tissue. Two configurations are analysed, the first with the four electrodes collinear and the second with one electrode removed from the line of the other three. It is found that the second electrode configuration can yield a value for the fibre rotation under the assumptions of the model.
