What is "pulse"

Pulse \Pulse\, n. [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. ? to swing, shake, ? to shake. Cf. Appeal, Compel, Impel, Push.]

1. (Physiol.) 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.

   1. To ascertain, by the sense of feeling, the condition of the arterial pulse.

   2. Hence, to sound one's opinion; to try to discover one's mind.

Pulse \Pulse\, n. [OE. puls, L. puls, pultis, a thick pap or pottage made of meal, pulse, etc. See Poultice, and cf. Pousse.] Leguminous plants, or their seeds, as beans, pease, etc.

Pulse \Pulse\, v. t. [See Pulsate, Pulse a beating.] To drive by a pulsation; to cause to pulsate. [R.]

"a throb, a beat," early 14c., from Old French pous, pulse (late 12c., Modern French pouls) and directly from Latin pulsus (in pulsus venarum "beating from the blood in the veins"), past participle of pellere "to push, drive," from PIE *pel- (6) "to thrust, strike, drive" (cognates: Greek pallein "to wield, brandish, swing," pelemizein "to shake, cause to tremble"). Extended usages from 16c. Figurative use for "life, vitality, essential energy" is from 1530s.

"to beat, throb," early 15c., from pulse (n.1) or else from Latin pulsare "to beat, throb," and in part from French. Related: Pulsed; pulsing.

"peas, beans, lentils," late 13c., from Old French pouls, pols and directly from Latin puls "thick gruel, porridge, mush," probably via Etruscan, from Greek poltos "porridge" made from flour, from PIE *pel- (1) "dust, flour" (see pollen; also compare poultice).

1. v. expand and contract rhythmically; beat rhythmically; "The baby's heart was pulsating again after the surgeon massaged it" [syn: pulsate, throb]

A pulse, in physiology, is the throbbing of arteries resulting from heartbeat. Pulse may also refer to:

In signal processing, the term pulse has the following meanings:

1. A rapid, transient change in the amplitude of a signal from a baseline value to a higher or lower value, followed by a rapid return to the baseline value.
2. A rapid change in some characteristic of a signal, e.g., phase or frequency, from a baseline value to a higher or lower value, followed by a rapid return to the baseline value.

In medicine, a pulse represents the tactile arterial palpation of the heartbeat by trained fingertips. The pulse may be palpated in any place that allows an artery to be compressed against a bone, such as at the neck ( carotid artery), on the inside of the elbow ( brachial artery), at the wrist ( radial artery), at the groin ( femoral artery), behind the knee ( popliteal artery), near the ankle joint ( posterior tibial artery), and on foot ( dorsalis pedis artery). Pulse (or the count of arterial pulse per minute) is equivalent to measuring the heart rate. The heart rate can also be measured by listening to the heart beat directly ( auscultation), traditionally using a stethoscope and counting it for a minute. The radial pulse is commonly measured using three fingers. This has a reason: the finger closest to the heart is used to occlude the pulse pressure, the middle finger is used get a crude estimate of the blood pressure, and the finger most distal to the heart (usually the ring finger) is used to nullify the effect of the ulnar pulse as the two arteries are connected via the palmar arches ( superficial and deep). The study of the pulse is known as sphygmology.

In music and music theory, the pulse consists of beats in a (repeating) series of identical yet distinct periodic short-duration stimuli perceived as points in time occurring at the mensural level. "This pulse is typically what listeners entrain to as they tap their foot or dance along with a piece of music (Handel, 1989), and is also colloquially termed the 'beat,' or more technically the 'tactus' (Lerdahl & Jackendoff, 1983)."

Pulse is the largest annual cultural, literary and sports festival of the All India Institute of Medical Sciences, New Delhi, India held for Medical Undergraduate students in India. It is held every year from September 16–22 . This week long extravaganza is the biggest inter-college festival of the medical fraternity of India with participation of medical and dental colleges all over India and even foreign medical colleges.

Pulse was an entertainment channel focusing on eSports as well as American extreme sports, classic films and mixed martial arts, broadcasting in the United Kingdom on British Sky Broadcasting.

The channel was re-branded from XLEAGUE.TV, an eSports channel. Several time-shift channels were available during the time of air - Pulse +30, Pulse +45 and Pulse +1. Pulse +30mins was the first one to be closed down, on 24 November 2008. Pulse +1 was the second, which closed down on 9 November 2008 and was replaced with HiTV. Two days later on 11 November 2008, a second timeshift, Pulse +45mins, was closed down, which suddenly fell off the air. However it did later return on 24 November 2008 after Pulse +30mins closed down. The Pulse +30mins EPG slot was replaced by OBE TV. Pulse was removed from the Sky EPG on 10 February 2009. Pulse +45mins was replaced by Rural TV on 2 March 2009.

It featured coverage of eSports and in this respect, it differs from other examples of video game programming in the country, such as Cybernet, which had a broader remit, to cover video games in general. The channel is closely paired to its own self-titled website. The online resource encourages community discussion, while also serving as a platform to organise tournaments and invitational events, some of which may later be screened, on the channel, via its flagship programme, The Match.

While the televised matches regularly feature members of recognised, successful gaming clans such as Team Dignitas, and individual victors of major gaming tournaments including Shaun "Apollo" Clark. Xleague.tv also encourages enthusiasts and non-professionals to get involved in the community (and thus, potentially, The Match) through the game-specific clubs and leagues set up in a way that ensures that players of like strength compete together.
