What's the difference between pulse and pulselessness?
Pulse
Definition:
(n.) Leguminous plants, or their seeds, as beans, pease, etc.
(n.) The beating or throbbing of the heart or blood vessels, especially of the arteries.
(n.) 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.
(v. i.) To beat, as the arteries; to move in pulses or beats; to pulsate; to throb.
(v. t.) To drive by a pulsation; to cause to pulsate.

(11) The diagnosis of an arterial injury may be readily apparent, but the excellent upper-extremity collateral circulation may create palpable distal pulses despite a significant proximal arterial injury.
(12) Diabetic retinopathy (an index of microangiopathy) and absence of peripheral pulses, amputation, or history of myocardial infarction, stroke, or transient ischemic attacks (as evidence of macroangiopathy) caused surprisingly little increase in relative risk for cardiovascular death.

(19) A method using selective saturation pulses and gated spin-echo MRI automatically corrects for this motion and thus eliminates misregistration artifact from regional function analysis.
(20) To date, a cognate action of E2 on the GnRH pulse generator has not been described.
Pulselessness
Definition:
(n.) The state of being pulseless.
Example Sentences:
(1) Occlusive thromboaortopathy, also known as "pulseless disease" or Takayasu's disease, was first described in 1908 by Takayasu, who observed cataracts and peculiar arteriovenous anastamoses around the optic papillae in a young woman.
(2) Takayasu disease is characterized by a pulseless condition which most often occurs in young females from Asian or South American areas.
(3) Two different algorithms were used one for ventricular fibrillation (VF) and pulseless ventricular tachycardia and one for asystole and pulseless bradycardia.

(12) Very high blood pressure in the absence of significant target organ impairment is an important clue to this subtype of hypertension and should lead to simple diagnostic techniques, such as Osler's maneuver (an attempt to palpate a pulseless radial artery) and radiographs of the soft tissues of the arms.
(13) This case highlights the fact that, irrespective of race, any patient who presents for the first time in pregnancy with pulseless hypertensive disease or other features suggestive of Takayasu's arteritis, should have their management in labour determined by the number of complications that are present.
