Key result
The quantitative electrokymograph was developed to record border-motion and densitometric changes in the heart and great vessels with a frequency response of 0 to 40 cycles per second.
The development of the quantitative electrokymograph provides a calibrated, easier-to-use instrument for recording cardiac border-motion and densitometric changes.

May support quantitative cardiac motion assessment; leaves open clinical validation and adoption.
The quantitative electrokymograph has been developed in an effort to provide an instrument which will be easier to operate than the electrokymographic equipment currently available. In addition, provision has been made for the recording of both border-motion phenomena and densitometric changes within the heart and great vessels. In the design of the instrument, considerable attention has been directed toward the development of a means whereby electrokymographic tracings may be calibrated. Care has also been exercised in the instrument's design in order to provide a frequency response that is essentially flat from 0 to 40 cycles per second.
