pulse
(puls) [L. pulsus, beating]1. Rate, rhythm, condition of arterial walls, compressibility and tension, and size and shape of the fluid wave of blood traveling through the arteries as a result of each heartbeat.
3. Throbbing caused by the regular contraction and alternate expansion of an artery as the wave of blood passes through the vessel; the periodic thrust felt over arteries in time with the heartbeat. See: illustrationA tracing of this is called a sphygmogram and consists of a series of waves in which the upstroke is called the anacrotic limb, and the downstroke (on which is normally seen the dicrotic notch), the catacrotic limb.
The normal resting pulse in adults is between 60 and 100 beats per minute. The resting pulse is faster, for example, in febrile patients, anemic or hypovolemic persons, persons in shock, and patients who have taken drugs that stimulate the heart, such as theophylline, caffeine, nicotine, or cocaine. It may be slower in well-trained athletes; in patients using beta blockers, calcium channel blockers, or other agents; and during sleep or deep relaxation.
Patient care
In patients complaining of chest pain, pulses should be assessed in at least two extremities (e.g., both radial arteries). A strong pulse on the right side with a weak one on the left may suggest an aortic dissection or a stenosis of the left subclavian artery. Young patients with high blood pressure should have pulses assessed simultaneously at the radial and femoral artery because a significant delay in the femoral pulse may suggest coarctation of the aorta. Patients with recent symptoms of stroke or claudication should have pulses checked at the carotid, radial, femoral, popliteal, and posterior tibial arteries, to see whether any palpable evidence of arterial insufficiency exists at any of these locations. If a decreased pulse is detected, further evaluation might include ultrasonography or assessments of the ankle brachial index. Patients who are lightheaded or dizzy or who notice palpitations may have detectable premature beats or other pulse irregularities (e.g., the irregularly irregular pulse of atrial fibrillation).

Differential diagnosis | aortic regurgitation |
Watson's water hammer pulse, also known as Corrigan's pulse or collapsing pulse, is the medical sign (seen in aortic regurgitation) which describes a pulse that is bounding and forceful,[1] rapidly increasing and subsequently collapsing,[2] as if it were the sound of a waterhammer that was causing the pulse. A water hammer was a Victorian toy in which a tube was half filled with fluid, the remainder being a vacuum. Each time the tube was inverted or shaken, the impact of the fluid at each end would sound like a hammer blow.[citation needed]
This is associated with increased stroke volume of the left ventricle and decrease in the peripheral resistance leading to the widened pulse pressure of aortic regurgitation.
Diagnosis[edit]
To feel a water hammer pulse: with the patient reclining, the examiner raises the patient's arm vertically upwards. The examiner grasps the muscular part of the patient's forearm. A water hammer pulse is felt as a tapping impulse which is transmitted through the bulk of the muscles. This happens because the blood that is pumped to the arm during systole is emptied very quickly due to the gravity effect on the raised arm. This results in the artery emptying back into the heart during diastole, increasing preload, and therefore increasing cardiac output, (as per the Frank–Starling mechanism) so that systolic blood pressure increases and a stronger pulse pressure can be palpated.[citation needed]
Causes[edit]
Water hammer pulse is commonly found when a patient has aortic regurgitation. It can also be seen in other conditions which are associated with a hyperdynamic circulation. A more comprehensive list of causes follows:[citation needed]
- Physiological
- Cardiac lesions
- Syndromes or high-output states
- Other causes
Eponym[edit]
'Watson's water hammer pulse' and 'Corrigan's pulse' refer to similar observations. However, the former usually refers to measurement of a pulse on a limb, while the latter refers to measurement of the pulse of the carotid artery.[1]
- 'Corrigan's pulse' is named for Sir Dominic Corrigan, the Irish physician, who characterized it in 1832.[3][4]
- 'Watson's water hammer pulse' is named for Thomas Watson, who characterized it in 1844.[1]
