| bigeminal pulse | A pulse in which the beats occur in pairs. Synonym: bigemina, coupled pulse, pulsus bigeminus. (05 Mar 2000) |
|---|
| bigeminal | Paired; double; twin. (05 Mar 2000) |
|---|---|
| bigeminal bodies | A bilateral single swelling of the roofplate of the embryonic midbrain that later in development becomes subdivided into a superior and an inferior colliculus. See: quadrigeminal bodies. Synonym: corpora bigemina. (05 Mar 2000) |
| bigeminal pregnancy | A pregnancy that may result from the fertilization of two separate ova or of a single ovum. See: twin. Synonym: bigeminal pregnancy. (05 Mar 2000) |
| bigeminal rhythm | That cardiac rhythm when each beat of the dominant rhythm (sinus or other) is followed by a premature beat, with the result that the heartbeats occur in pairs (bigeminy). Synonym: coupled rhythm. (05 Mar 2000) |
| abdominal pulse | The soft, compressible aortic pulse occurring in certain abdominal disorders. Synonym: pulsus abdominalis. (05 Mar 2000) |
| alternating pulse | Mechanical alternation, a pulse regular in time but with alternate beats stronger and weaker, often detectable only with the sphygmomanometer and usually indicating serious myocardial disease. Synonym: pulsus alternans. (05 Mar 2000) |
| amplitude of pulse | See: average pulse magnitude, peak magnitude. (05 Mar 2000) |
| anacrotic pulse | A pulse wave showing one or more notches or indentations on its rising limb that are sometimes detectable by palpation. Synonym: pulsus anadicrotus. (05 Mar 2000) |
| asynchronous pulse generator | A generator in which the rate of discharge is independent of the natural activity of the heart. Synonym: fixed rate pulse generator. (05 Mar 2000) |
| 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) |
| 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) |
