| pulsus myurus | 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) |
|---|---|
| pulsus paradoxus | 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) |
| pulsus parvus | A pulse of small amplitude, as in aortic stenosis. (05 Mar 2000) |
| pulsus parvus et tardus | Small, late pulse considered typical of severe aortic stenosis. (05 Mar 2000) |
| pulsus quadrigeminus | A pulse in which the beats are grouped in fours, a pause following every fourth beat. Synonym: pulsus quadrigeminus. (05 Mar 2000) |
| pulsus rarus | A pulse with pathologically gradual upstroke typical of severe aortic stenosis. See: plateau pulse. Synonym: pulsus rarus. (05 Mar 2000) |
| pulsus respiratione intermittens | 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) |
| pulsus tardus | A pulse with pathologically gradual upstroke typical of severe aortic stenosis. See: plateau pulse. Synonym: pulsus rarus. (05 Mar 2000) |
| pulsus tremulus | A feeble fluttering pulse. (05 Mar 2000) |
| pulsus trigeminus | A pulse in which the beats occur in trios, a pause following every third beat. Synonym: pulsus trigeminus. (05 Mar 2000) |
| pulsus vacuus | A very weak pulse hardly distending the arterial wall. (05 Mar 2000) |
| pulsus venosus | A pulsation occurring in the veins, especially the internal jugular vein. Synonym: pulsus venosus. (05 Mar 2000) |
