kymograph[′kī·mə‚graf] (industrial engineering) A device used to measure extremely short work time intervals by using a system of transducers that are activated by an operator performing a job, with the impulses recorded as a function of time. (medicine) A device for recording internal body movements by making tracings with a stylus on a revolving smoked drum. Kymograph an instrument that graphs certain physiological processes, such as heartbeat, respiration, and muscle contractions. A mechanical kymograph was used for the first time by the German physiologist K. Ludwig in 1847 to record changes in blood pressure. The apparatus consisted of a metal drum, covered with smoked paper and evenly rotated by a clock mechanism. A stylus attached to a rod and connected to the contracting heart, muscle, or other functioning organ describes a curve on the drum. The speed of rotation of the kymograph is regulated by the movement of a friction clutch along the axis and depends on the dimensions of an air brake. Electrokymographs are used for investigations demanding greater accuracy. These kymographs ensure a constant but easily regulated speed of movement. The driving drum of the electrokymograph is set in motion by an electric motor. I. N. D’IAKONOVA kymographenUK
ky·mo·graph (kī'mō-graf), An obsolete instrument for recording wavelike motions or modulation, especially for recording variations in blood pressure; it consists of a drum usually revolved by clockwork and covered with smoked paper upon which the curve is inscribed by a stylet or other writing point. [G. kyma, wave, + graphō, to record] kymograph (kī′mə-grăf′)n. An instrument for recording variations in pressure, as of the blood, or in tension, as of a muscle, by means of a pen or stylus that marks a rotating drum.
ky′mo·graph′ic adj.ky·mo·graph (kī'mō-graf) An instrument for recording wavelike motions or modulation of body organs (e.g., heart, great blood vessels); it consists of a drum revolved by clockwork and covered with smoked paper on which the curve is inscribed by a writing point. [G. kyma, wave, + graphō, to record]kymograph the revolving drum used in investigations of the physiology of nerves and muscles. Usually, it is capable of rotating at different known speeds and carries a piece of graph paper on which a trace is produced by a lever connected to the physiological preparation.kymographenUK
