APA Dictionary of Psychology
pulse
- n.
- the pressure waves caused by rhythmic contraction and relaxation of the walls of arteries as blood is pumped from the heart. The pulse, which can be detected manually at superficial arteries, provides a measure of the heart rate. The strength of the pulse at various points in the body (e.g., the ankle) gives an indication of the adequacy of circulation.
- an increase followed by a decrease in magnitude of a signal.
