| cannonball pulse | <radiology> Corrigan's sign: increased pulse at wrist, aortic insufficiency, widened pulse pressure due to increased stroke volume, diastolic regurgitation (12 Dec 1998) |
|---|---|
| capillary pulse | The alternate rhythmical blanching and reddening of a capillary area, as seen under the nails or in the lip, upon gentle compression; a sign of arteriolar dilation, well seen in aortic insufficiency. (05 Mar 2000) |
| radial pulse | The pulse as appreciated at the radial artery usually in the wrist. (05 Mar 2000) |
| vagus pulse | A slow pulse due to the inhibitory action of the vagus nerve on the heart. (05 Mar 2000) |
| radiofrequency pulse | In nuclear magnetic resonance, a short electromagnetic signal used to change the direction of the magnetic field. See: sequence pulse. (05 Mar 2000) |
| gaseous pulse | A soft, full, but feeble pulse. (05 Mar 2000) |
| 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) |
