Optical mapping provides an opportunity to study the propagation of electric activation across the heart surface. In order to do so, however, it is necessary to correct for artifact introduced by heart wall motion This paper describes a novel technique that enables electrical propagation on the heart surface to be reconstructed in the absence of pharmacological uncouplers which are commonaly used. In this approach, image registration methods are used retrospectively to correct for heart wall motion. Image registration substantially reduced motion artifact and enabled the propagation of electrical activation to be reconstructed accurately with respect to well-defined material points on the heart surface. Image registration also enables action potential duration to be estimated reliably at defined material locations in the absence of electro-mechanical uncouplers.
