Abstract: PULSE GENERATING AND SHAPING CIRCUITS GENERATE A COMOSITE OUTPUT SIGNAL SIMULATING AN ECG SIGNAL FOR DISPLAY ON CATHODE-RAY PRESENTATION EQUIPMENT. THE CIRCUITS ARE SELECTIVELY CONTROLLABLE TO PROVIDE THE QRS, P AND T WAVES OF INDIVIDUALLY PRESCRIBED AMPLITUDES AND VARIABLE RELATIVE LOCATIONS ALONG THE X-AXIS. THE QRS WAVE MAY BE MADE TO EXTEND EITHER POSITIVELY IN THE Y DIRECTION, OR INVERTED TO EXTEND NEGATIVELY. A FURTHER ASPECT IS THE PROVISION OF ADDITIONAL PULSE SIGNAL GENERATING CIRCUITRY FOR PRODUCING A PULSE TRAIN REPRESENTTIVE OF BLOOD PRESSURE AS MEASURED WITHIN THE AORTA.
