Abstract: A signal acquisition and output system controlled by a microcomputer was used to extend the function of polygraph (Model SJ-41). As a result, its frequency response increased to 1000Hz. His bundle electrograms of the rabbit and guinea pig in situ could be clealy recorded by using this technique.
