PulsePulse, 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.
☞ 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.
PulsePulse, v. i. To beat, as the arteries; to move in pulses or beats; to pulsate; to throb. Ray.
PulsePulse, v. t. [See Pulsate, Pulse a beating.] To drive by a pulsation; to cause to pulsate. [R.]

In medicine, one's 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), at the wrist (radial artery), behind the knee (popliteal artery), on the inside of the elbow (brachial artery), and near the ankle joint (posterior tibial artery). The pulse can also be measured by listening to the heart beat directly (auscultation), traditionally using a stethoscope.
The pulse is a decidedly low tech/high yield and antiquated term still useful at the bedside in an age of computational analysis of cardiac performance. Claudius Galen was perhaps the first physiologist to describe the pulse. The pulse is an expedient tactile method of determination of systolic blood pressure to a trained observer. Diastolic blood pressure is non-palpable and unobservable by tactile methods, occurring between heartbeats.
Pressure waves generated by the heart in systole moves the arterial walls. Forward movement of blood occurs when the boundaries are pliable and compliant. These properties form enough to create a palpable pressure wave.
The heart rate may be greater or lesser than the pulse rate depending upon physiologic demand. In this case, the heart rate is determined by auscultation or audible sounds at the heart apex, in which case it is not the pulse. The pulse deficit (difference between heart beats and pulsations at the periphery) is determined by simultaneous palpation at the radial artery and auscultation at the heart apex.
Pulse velocity, pulse deficits and much more physiologic data are readily and simplistically visualized by the use of one or more arterial catheters connected to a transducer and oscilloscope. This invasive technique has been commonly used in intensive care since the 1970s.
The rate of the pulse is observed and measured by tactile or visual means on the outside of an artery and is recorded as beats per minute or BPM.
The pulse may be further indirectly observed under light absorbances of varying wavelengths with assigned and inexpensively reproduced mathematical ratios. Applied capture of variances of light signal from the blood component hemoglobin under oxygenated vs. deoxygenated conditions allows the technology of pulse oximetry.

The pulse rate can be used to check overall heart health and fitness level. Generally lower is better, but bradycardias can be dangerous. Symptoms of a dangerously slow heartbeat include weakness, loss of energy and fainting.
Several pulse patterns can be of clinical significance. These include:
A collapsing pulse is a sign of hyperdynamic circulation.
Chinese medicine has focused on the pulse in the upper limbs for several centuries. The concept of pulse diagnosis is essentially a treatise based upon palpation and observations of the radial and ulnar volar pulses at the readily accessible wrist.

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
