| 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) |
| triphammer pulse | <radiology> Corrigan's sign: increased pulse at wrist, aortic insufficiency, widened pulse pressure due to increased stroke volume, diastolic regurgitation (12 Dec 1998) |
| jugular pulse | The venous pulse as observed in the jugular veins of the neck, usually the deep jugular veins. (05 Mar 2000) |
| undulating pulse | A toneless pulse in which there is a succession of waves without character or force. Synonym: pulsus fluens. (05 Mar 2000) |
| unequal pulse | Differing strength of pulse in the same artery between the right and left of the circulation. (05 Mar 2000) |
| Kussmaul's paradoxical pulse | An exaggeration of the normal variation in the pulse volume with respiration, becoming weaker with inspiration and stronger with expiration; characteristic of cardiac tamponade, rare in constrictive pericarditis; so called because these changes are independent of changes in the cardiac rate as measured directly or by electrocardiogram. Synonym: pulsus paradoxus, pulsus respiratione intermittens. (05 Mar 2000) |
