Action potential — In physiology, an action potential is a short lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, called… … Wikipedia
Cardiac action potential — The cardiac action potential is a specialized action potential in the heart, with unique properties necessary for function of the electrical conduction system of the heart.The cardiac action potential differs significantly in different portions… … Wikipedia
Pacemaker potential — In the heart, the pacemaker potential is the voltage created by impulses from an artificial electronic pacemaker or the SA node which drives the rhythmic firing of the heart.The pacemaker potential brings the membrane potential to the threshold… … Wikipedia
potential — 1. Capable of doing or being, although not yet doing or being; possible, but not actual. 2. A state of tension in an electric source enabling it to do work under suitable conditions; in relation to electricity, p. is analogous to the temperature… … Medical dictionary
Cardiac pacemaker — The contractions of the heart are controlled by chemical impulses, which fire at a rate which controls the beat of the heart.The cells that create these rhythmical impulses are called pacemaker cells, and they directly control the heart rate.… … Wikipedia
Biological pacemaker — The heart is endowed with specialized excitatory and conducting cells that are responsible for the generation and conduction of rhythmic impulses and contractions throughout the heart. If these cells are damaged by disease, the implantation of an … Wikipedia
Resting potential — The relatively static membrane potential of quiescent cells is called the resting membrane potential (or resting voltage), as opposed to the specific dynamic electrochemical phenomena called action potential and graded membrane potential. Apart… … Wikipedia
triggered automaticity — pacemaker activity occurring as a result of a propagated or stimulated action potential, such as an afterdepolarization, in cells or tissues not normally displaying a spontaneous automaticity … Medical dictionary
Neural oscillation — is rhythmic or repetitive neural activity in the central nervous system. Neural tissue can generate oscillatory activity in many ways, driven either by mechanisms localized within individual neurons or by interactions between neurons. In… … Wikipedia
cardiovascular disease — Introduction any of the diseases, whether congenital or acquired, of the heart and blood vessels (blood vessel). Among the most important are atherosclerosis, rheumatic heart disease, and vascular inflammation. Cardiovascular diseases are a … Universalium
