| pulse wave | The progressive expansion of the arteries occurring with each contraction of the left ventricle of the heart. (05 Mar 2000) |
|---|---|
| sequence pulse | In magnetic resonance imaging, the series of radiofrequency signals used to shift the magnetic field to change proton orientation. (05 Mar 2000) |
| soft pulse | A pulse that is readily extinguished by pressure with the finger. (05 Mar 2000) |
| nail pulse | A capillary pulse seen through the nail. (05 Mar 2000) |
| standby pulse generator | A generator which suppresses its output in response to natural ventricular activity but which, in the absence of such activity, functions as an asynchronous pulse generator. Synonym: demand pulse generator, standby pulse generator. (05 Mar 2000) |
| demand pulse generator | A generator which suppresses its output in response to natural ventricular activity but which, in the absence of such activity, functions as an asynchronous pulse generator. Synonym: demand pulse generator, standby pulse generator. (05 Mar 2000) |
| dicrotic pulse | A pulse which is marked by a double beat, the second, due to a palpable dicrotic wave, being weaker than the first. Synonym: pulsus duplex. (05 Mar 2000) |
| quadrigeminal pulse | A pulse in which the beats are grouped in fours, a pause following every fourth beat. Synonym: pulsus quadrigeminus. (05 Mar 2000) |
| Quincke's pulse | The capillary pulse as appreciated in the finger and toenails during aortic regurgitation; ebb and flow is seen. Synonym: Quincke's sign. (05 Mar 2000) |
| intermittent pulse | Irregularity of the heart due to extrasystoles which are too weak to open the semilunar valves; often owing to the long pause following the premature beat, extra long pauses equal to two regular cycles occur from time to time between pulse beats. Synonym: pulsus intercidens. (05 Mar 2000) |
| irregular pulse | Variation in rate of impulses in an artery due to cardiac arrhythmia. (05 Mar 2000) |
| tense pulse | A hard, full pulse but without very wide excursions, resembling the vibration of a thick cord. Synonym: cordy pulse. (05 Mar 2000) |
| thready pulse | A small fine pulse, feeling like a small cord or thread under the finger. Synonym: pulsus filiformis. (05 Mar 2000) |
| entoptic pulse | An intermittent phose synchronous with the pulse. (05 Mar 2000) |
| trigeminal pulse | A pulse in which the beats occur in trios, a pause following every third beat. Synonym: pulsus trigeminus. (05 Mar 2000) |
