| pulse height analyzer | Electronic circuitry that determines the energy of scintillations recorded by a detector, allowing use of a discriminator to select for photons of a specific type. (05 Mar 2000) |
|---|---|
| pulse period | The reciprocal of the repetition rate; e.g., the interval between leading edges of successive pulses. (05 Mar 2000) |
| pulse pressure | The variation in blood pressure occurring in an artery during the cardiac cycle; it is the difference between the systolic or maximum and diastolic or minimum pressure's. (05 Mar 2000) |
| pulse radiolysis | Use of a pulse of X-rays or fast electrons to generate free radicals for spectroscopic examination. (12 Dec 1998) |
| pulse rate | Rate of the pulse as observed in an artery; recorded as beats per minute. (05 Mar 2000) |
| pulse therapy | A short, intensive course of pharmacotherapy, usually given at intervals such as weekly or monthly; often used in chemotherapy of malignancy. (05 Mar 2000) |
| 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) |
