Pulse, n. Etym: [OE. pous, OF. pous, F. pouls, fr. L. pulsus (sc.
venarum), the beating of the pulse, the pulse, from pellere, pulsum,
to beat, strike; cf. Gr. Appeal, Compel, Impel, Push.]
1. (Physiol.)
Definition: The beating or throbbing of the heart or blood vessels,
especially of the arteries.
Note: In an artery the pulse is due to the expansion and contraction
of the elastic walls of the artery by the action of the heart upon
the column of blood in the arterial system. On the commencement of
the diastole of the ventricle, the semilunar valves are closed, and
the aorta recoils by its elasticity so as to force part of its
contents into the vessels farther onwards. These, in turn, as they
already contain a certain quantity of blood, expand, recover by an
elastic recoil, and transmit the movement with diminished intensity.
Thus a series of movements, gradually diminishing in intensity, pass
along the arterial system (see the Note under Heart). For the sake of
convenience, the radial artery at the wrist is generally chosen to
detect the precise character of the pulse. The pulse rate varies with
age, position, sex, stature, physical and psychical influences, etc.
2. Any measured or regular beat; any short, quick motion, regularly
repeated, as of a medium in the transmission of light, sound, etc.;
oscillation; vibration; pulsation; impulse; beat; movement.
The measured pulse of racing oars. Tennyson.
When the ear receives any simple sound, it is struck by a single
pulse of the air, which makes the eardrum and the other membranous
parts vibrate according to the nature and species of the stroke.
Burke.
Pulse glass, an instrument consisting to a glass tube with terminal
bulbs, and containing ether or alcohol, which the heat of the hand
causes to boil; -- so called from the pulsating motion of the liquid
when thus warmed. Pulse wave (Physiol.), the wave of increased
pressure started by the ventricular systole, radiating from the
semilunar valves over the arterial system, and gradually disappearing
in the smaller branches.
the pulse wave travels over the arterial system at the rate of about
29.5 feet in a second. H. N. Martin.
– To feel one's pulse. (a) To ascertain, by the sense of feeling,
the condition of the arterial pulse. (b) Hence, to sound one's
opinion; to try to discover one's mind.
