pulse (puls) the rhythmic expansion of an artery that may be felt with the finger.
Corrigan's pulse
Corrigan's pulse
alternating pulse one with regular alternation of weak and strong beats without changes in cycle length.
anacrotic pulse one in which the ascending limb of the tracing shows a transient drop in amplitude.
bigeminal pulse one in which two beats occur in rapid succession, the groups of two being separated by a longer interval.
cannonball pulse Corrigan's p.
capillary pulse Quincke's p.
catadicrotic pulse one in which the descending limb of the tracing shows two small notches.
Corrigan's pulse jerky pulse with full expansion and sudden collapse.
dicrotic pulse a pulse characterized by two peaks, the second peak occurring in diastole and being an exaggeration of the dicrotic wave.
entoptic pulse a phose occurring with each pulse beat.
hard pulse one characterized by high tension.
jerky pulse one in which the artery is suddenly and markedly distended.
paradoxical pulse one that markedly decreases in size during inhalation, as often occurs in constrictive pericarditis.
pistol-shot pulse Corrigan's p.
plateau pulse one that is slowly rising and sustained.
quadrigeminal pulse one with a pause after every fourth beat.
Quincke's pulse alternate blanching and flushing of the nail bed due to pulsation of subpapillary arteriolar and venous plexuses; seen in aortic insufficiency and other conditions and occasionally in normal persons.
Riegel's pulse one that is smaller during respiration.
thready pulse one that is very fine and scarcely perceptible.
tricrotic pulse one in which the tracing shows three marked expansions in one beat of the artery.
trigeminal pulse one with a pause after every third beat.
vagus pulse a slow pulse.
venous pulse the pulsation over a vein, especially over the right jugular vein. 
)
Normal jugular venous pulse: A, a positive wave due to contraction of the right atrium; C, a positive deflection due to bulging of the tricuspid valve toward the atria at the onset of ventricular contraction; X, a negative deflection due to atrial relaxation; V, a positive deflection due to filling of the right atrium against the closed tricuspid valve during ventricular contraction; Y, a negative deflection due to emptying of the right atrium upon ventricular relaxation.
water-hammer pulse Corrigan's p.
wiry pulse a small, tense pulse.
Cor·ri·gan's pulse (kôr  -g ns)n. See water-hammer pulse. |
Corrigan's pulse
Etymology: Dominic J. Corrigan, Irish physician, 1802-1880
a bounding pulse in which a great surge is felt, followed by a sudden and complete absence of force or fullness in the artery. This kind of pulse is associated with aortic regurgitation and occurs in excited emotional states; in various cardiac conditions, including patent ductus arteriosus; and as a result of systemic arteriosclerosis. Also called collapsing pulse, water-hammer pulse.
Corrigan's pulse
a jerky pulse with full expansion and full collapse.
Corrigan's pulse
Cardiology A clinical sign of aortic regurgitation 2º to ↑ pulse pressure, which is characterized by a bounding carotid pulse and a rapid downstroke. See Aortic regurgitation.
