| piston pulse | <radiology> Corrigan's sign: increased pulse at wrist, aortic insufficiency, widened pulse pressure due to increased stroke volume, diastolic regurgitation (12 Dec 1998) |
|---|---|
| mousetail pulse | A pulse marked by a wave, the apex of which is reached suddenly and which then subsides very gradually. Synonym: mousetail pulse. (05 Mar 2000) |
| movable pulse | The lateral movement of a strongly pulsating tortuous artery. (05 Mar 2000) |
| plateau pulse | A slow, sustained pulse. (05 Mar 2000) |
| wiry pulse | A small, fine, incompressible pulse. (05 Mar 2000) |
| cordy pulse | A hard, full pulse but without very wide excursions, resembling the vibration of a thick cord. Synonym: cordy pulse. (05 Mar 2000) |
| Corrigan's pulse | <clinical sign> A full hard pulse followed by a sudden collapse easily palpated and occurring in aortic regurgitation. Synonym: Corrigan's pulse. (05 Mar 2000) |
| coupled pulse | A pulse in which the beats occur in pairs. Synonym: bigemina, coupled pulse, pulsus bigeminus. (05 Mar 2000) |
| half amplitude pulse duration | The time, in milliseconds, required for a wave form to reach half of its full magnitude. (05 Mar 2000) |
| hard pulse | A pulse that strikes forcibly against the tip of the finger and is with difficulty compressed, suggesting hypertension. Synonym: pulsus durus. (05 Mar 2000) |
| pulse | <cardiology, physiology> The impulse transmitted to arteries by contraction of the left ventricle of the heart. Customarily palpated at the radial artery in the wrist. The pulse can provide information concerning the number of cardiac contractions per minute (rate) and the overall regularity of the contractions (rhythm). (15 Dec 1997) |
| pulse chase | <biochemistry> An experimental protocol used to determine cellular pathways, such as precursor product relationships. A sample organism, cell or cellular organelle), is exposed for a relatively brief time to a radioactively labelled molecule, the pulse. It is then replaced with an excess of the unlabelled molecule, the chase (cold chase). The sample is then examined at various later times to determine the fate of radioactivity incorporated during the pulse. (15 Dec 1997) |
| pulse-chase experiment | An experiment in which an enzyme, a metabolic pathway, a culture of cells, etc., interacts with a brief addition (pulse) of a labelled compound followed by its removal and replacement (chase) by an excess of unlabelled compound. (05 Mar 2000) |
| pulse deficit | The absence of palpable pulse waves in a peripheral artery for one or more heart beats, as is often seen in atrial fibrillation, the number of such missing pulse waves (usually expressed as heart rate minus pulse rate per minute). (05 Mar 2000) |
| pulse duration | The interval between onset of the leading edge and the end of the trailing edge of a pulse wave. (05 Mar 2000) |
