Analog computer simulation of heart action

The significance of the work described lies in the potential of the technique explored. The analog computer simulation of heart action is presented primarily to illustrate that potential, which, though interesting, is only a necessary first step in an investigation capable of extending knowledge far beyond its present bounds. There is a certain risk in presenting the limited results of progress to date, particularly to an audience represented by different professions, somewhat divergent interests, and certainly varied talents. However, we gladly take that risk in the hope that others will be encouraged to improve upon our work, pervert the suggested technique to their own ends, and thereby develop better tools for the job they must do.
