Sphygmograph

Definition

A device that functions as a graphic printer of the waveform of the arterial pulse. This instrument usually includes a lever, the short end of which rests on the radial artery at the wrist, its long end being provided with a stylet which records (usually on a moving paper) the excursions of the pulse. The waveform typically consists of a curve having a sudden rise, followed by a sudden fall, after which there is a gradual descend marked by a number of secondary elevations. This GMDN code may reflect old technology.
