Home > Specialties > Sphygmographs


Definition : Graphical recorders designed to record the waveform, strength, and variations of the arterial pulse. These recorders usually consist of a lever, the short end of which rests on a superficial artery, typically the radial artery at the wrist; a pressure sensor; and a stylet, which makes a graphical record (usually on a moving paper) of the excursions of the pulse. Sphygmographs are used for noninvasive evaluation and recording of the pulse strength and its variations.
