  • Interesting fact: The first known heart medicine was discovered in an English garden. In 1799, physician John Ferriar noted the effect of dried leaves of the common foxglove plant, digitalis purpurea, on heart action. Still used in heart medications, digitalis slows the pulse and increases the force of heart contractions and the amount of blood pumped per heartbeat.
    • Pulse 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.""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."
    • n Pulse Leguminous plants, or their seeds, as beans, pease, etc. "If all the world
      Should, in a pet of temperance, feed on pulse."
    • Pulse (Physiol) The beating or throbbing of the heart or blood vessels, especially of the arteries.
    • v. i Pulse To beat, as the arteries; to move in pulses or beats; to pulsate; to throb.
    • v. t Pulse To drive by a pulsation; to cause to pulsate.

  • Interesting fact: The turtle has the lowest pulse rate of any animal: 13 beats per minute.
    • n pulse A beat; a stroke; especially, a measured, regular, or rhythmical beat; a short, quick motion regularly repeated, as in a medium of the transmission of light, sound, etc.; a pulsation; a vibration.
    • n pulse Specifically, in physiology, the series of rhythmically recurring maxima of fluid tension in any blood-vessel, consequent on the contractions of the heart. These may be perceived by palpation, and recorded by the sphygmograph, and often produce a visible effect in dilating the vessel, or causing a lateral movement of it. The pulse is for the most part confined to the arteries, but a venous pulse occurs (see below). There is one arterial pulse for each ventricular systole; but in disease a ventricular systole may be too feeble to produce a sensible pulsation in a distant artery, as at the wrist, or again each pulsation may be double. (See dicrotic pulse.) The features of the pulse are the times between successive pulsations, the maxima and minima of pressure, and the way in which the tension changes from maximum to minimum and to maximum again, represented in the form of the sphygmographic tracing. The normal pulse exhibits approximately equal and equidistant maxima, the rate being in adults between 70 and 80 (see pulse-rate); the rise of pressure is sharp, the fall slow with only a slight dicrotic wave; the extent of change (amplitude) is not excessive; and the tension of the blood in the vessel is neither too high nor too low. As taken with Basch's sphygonomanometer, the radial (maximum) tension in health usually lies between 135 and 165 millimeters mercury.
    • n pulse In music, same as beat or accent.
    • n pulse Figuratively, feeling; sentiment; general opinion, drift, tendency, or movement, private or public: as, the pulse of an occasion; the pulse of the community.

  • Interesting fact: When you put a seashell to your ear, the sound you hear is not the waves, but actually the echo of the blood pulsing in your own ear.
