| standby 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) |
| demand 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) |
| dicrotic pulse | A pulse which is marked by a double beat, the second, due to a palpable dicrotic wave, being weaker than the first. Synonym: pulsus duplex. (05 Mar 2000) |
