| FADS | fetal akinesia deformation sequence |
|---|---|
| FAV | facio-auriculovertebral [sequence]; feline ataxia virus; floppy aortic valve; fowl adenovirus |
| FRHS | fast-repeating high sequence |
| FRV | full-length retroviral [sequence]; functional residual volume |
| IGS | image-guided surgery; inappropriate gonadotropin secretion; internal guide sequence |
| atrial synchronous pulse generator | A ventricular stimulating pulse whose rate of discharge is directly determined by the atrial rate. Synonym: atrial triggered pulse generator. (05 Mar 2000) |

| atrial triggered pulse generator | A ventricular stimulating pulse whose rate of discharge is directly determined by the atrial rate. Synonym: atrial triggered pulse generator. (05 Mar 2000) |
| average pulse magnitude | <physics> The amplitude of pulse averaged throughout its duration; identical with peak amplitude for a square wave or pulse without droop. (05 Mar 2000) |
| bigeminal pulse | A pulse in which the beats occur in pairs. Synonym: bigemina, coupled pulse, pulsus bigeminus. (05 Mar 2000) |
| bisferious pulse | An arterial pulse with peaks that may be palpable. Synonym: pulsus bisferiens. (05 Mar 2000) |
| bulbar pulse | A jugular pulse supposed to indicate tricuspid insufficiency. (05 Mar 2000) |
| 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) |
