Abstract

An electro-anatomical model of the mammalian His/Purkinje system includes a shell simulating the anatomy of at least a portion of a mammalian heart. The shell has a hollow interior and a first port providing an aperture to the interior of the shell. A plug is inserted in the first port so that a surface of the plug is exposed to the interior of the shell. An electrical circuit provides signals to electrodes in the plug which simulate the electrical signals generated by the bundle of His/Purkinje system in vivo. A second port provides access to the interior of the shell for an introducer catheter to locate the simulated bundle of His and to insert a pacing lead therein. The model is useful for developing tools for His pacing and for training users in techniques for implanting His pacing leads.
