  • (20) Heartbeat, which originally starred Nick Berry as a London policeman transferred to a north Yorkshire village, was for years a mainstay of ITV's Sunday night schedule, attracting audiences of 15 million viewers in its 1990s heyday.

Pulsation


Definition:

  • (n.) A beating or throbbing, especially of the heart or of an artery, or in an inflamed part; a beat of the pulse.
  • (n.) A single beat or throb of a series.
  • (n.) A stroke or impulse by which some medium is affected, as in the propagation of sounds.
  • (n.) Any touching of another's body willfully or in anger. This constitutes battery.

Example Sentences:
