| 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) |

| rate, pulse | The pulse rate is most often taken at the wrist. It measures the number of pulsations in the radial artery each minute. (12 Dec 1998) |
| venous pulse | A pulsation occurring in the veins, especially the internal jugular vein. Synonym: pulsus venosus. (05 Mar 2000) |
| ventricular inhibited 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) |
| ventricular synchronous pulse generator | A pulse which delivers its output synchronously with naturally occurring ventricular activity but which, in the absence of such activity, functions as an asynchronous pulse generator. Synonym: ventricular triggered pulse generator. (05 Mar 2000) |
| ventricular triggered pulse generator | A pulse which delivers its output synchronously with naturally occurring ventricular activity but which, in the absence of such activity, functions as an asynchronous pulse generator. Synonym: ventricular triggered pulse generator. (05 Mar 2000) |
| vermicular pulse | A small rapid pulse, giving a wormlike sensation to the finger. (05 Mar 2000) |
| carotid pulse | The pulse of the carotid arteries in the neck. (05 Mar 2000) |
| catacrotic pulse | A pulse in which there is an upward notch interrupting the descending limb of the sphygmogram. Synonym: pulsus catacrotus. (05 Mar 2000) |
| catadicrotic pulse | A catacrotic pulse in which there are two interrupting upward notches. Synonym: pulsus catadicrotus. (05 Mar 2000) |
| respiratory pulse | Waxing and waning of any pulsation produced by respiration. (05 Mar 2000) |
| reversed paradoxical pulse | A pulse in which the amplitude increases with inspiration and decreases with expiration, as observed in some cases of tricuspid insufficiency and during A-V dissociation with sinus arrhythmia. (05 Mar 2000) |
| Riegel's pulse | A pulse that diminishes in volume during expiration. (05 Mar 2000) |
| guttural pulse | A pulsation felt in the throat. (05 Mar 2000) |
| water-hammer pulse | <radiology> Corrigan's sign: increased pulse at wrist, aortic insufficiency, widened pulse pressure due to increased stroke volume, diastolic regurgitation (12 Dec 1998) |
