ABSTRACT:
This invention is a system for generating electrocardiogram waveforms which can be used for many purposes. The system provides a counter whose outputs are applied to a group of gates in different combinations. The outputs from the gates are applied to an integrating circuit which converts the pulse amplitude and the widths of the outputs from the gates into analog signals whose slopes depend upon the widths of the pulses applied to the integrator. Any type of cardiogram can be analyzed initially and broken into its components. These individual components and their sequence determine the connections from the outputs of the counter to the inputs of the gates.
