capture (redirected from Regulator capture)

capture /cap·ture/ (kap´cher)

1. to seize or catch.

2. the coalescence of an atomic nucleus and a subatomic particle, usually resulting in an unstable mass.

---

atrial capture  depolarization of the atria in response to a stimulus either originating elsewhere in the heart or pacemaker-induced.

ventricular capture  depolarization of the ventricles in response to an impulse originating either in the supraventricular region or in an artificial pacemaker.

cap·ture (kpchr)

n.

The act of catching, taking, or holding a particle or impulse.

capture

[kap′chər]

1 the catching and holding of a nuclear particle, as an electron, or an electrical impulse originating elsewhere.

2 (in cardiology) the capture of control of the atria or ventricles after a period of independent beating caused by ectopic beats or an atrioventricular block.

3 (in cardiology) the ability of a pacemaker to electrically stimulate a cardiac chamber.

CAPTURE

c7E3 Fab Antiplatelt Therapy in Unstable Refractory Angina. A trial which investigated whether serum troponin T levels can identify patients most likely to benefit from platelet glycoprotein IIb/IIIa-receptor antibody abciximab therapy to reduce the incidence of cardiac events before and during coronary angioplasty
Conclusion Serum troponin T levels were effective for identifying such patients

capture [kap´choor]

1. the production of a ventricular complex from a supraventricular source following a period of atrioventricular dissociation.

2. in cardiac pacing terminology, the successful pacing of the heart by a pulse generator.

capture

the snaring and restraint of an escaped domesticated animal or a feral animal. It requires safety for the captor and the subject. Includes physical means of trap cages, the thrown lariat, a handheld net for small companion animals. Thrownets for birds are still favored by lay persons. Veterinarians are more inclined to use immobilizing agents delivered by darts from bows and arrows or from dart guns. See also restraint.

capture-mark-release-recapture

technique for establishing the nature of animal movements and the size of populations.

capture shock syndrome

in recently captured animals with death 1-6 hours after capture. Signs include shallow, rapid respiration, tachycardia, physical collapse, hyperthermia, small pulse, elevated CPK levels, general vascular congestion at necropsy.

capture stress syndrome

stress syndrome in wild animals in captivity.

capture

Cardiac pacing Depolarization of the atria and/or ventricles by an electrical stimulus delivered by an artificial pacemaker; one-to-one capture occurs when each electrical stimulus causes a corresponding depolarization. Cf Stimulation threshold.
