  • 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

  • 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

  • Atrial action potential — The atrial action potential are action potentials that occur in the heart atrium. See cardiac action potential for more information …   Wikipedia

  • Pacemaker action potential — A pacemaker action potential is the kind of action potential that provides a reference rhythm for the network. This contrasts with pacemaker potential or current which drives rhythmic modulation of firing rate.Some pacemaker action potentials… …   Wikipedia

  • Quantitative models of the action potential — In neurophysiology, several mathematical models of the action potential have been developed, which fall into two basic types. The first type seeks to model the experimental data quantitatively, i.e., to reproduce the measurements of current and… …   Wikipedia

  • Heart rate — is the number of heartbeats per unit of time, typically expressed as beats per minute (bpm). Heart rate can vary as the body s need to absorb oxygen and excrete carbon dioxide changes, such as during exercise or sleep. The measurement of heart… …   Wikipedia

  • Heart sounds — Front of thorax, showing surface relations of bones, lungs (purple), pleura (blue), and heart (red outline). The location of best auscultation for each heart valve are labeled with M , T , A , and P . First heart sound: caused by atrioventricular …   Wikipedia

  • Action Park — was a waterpark/motor themed park open from 1978 to 1996 in Vernon Township, New Jersey, on the property of the former Vernon Valley / Great Gorge ski area, today Mountain Creek. It featured three separate attraction areas: an alpine slide;… …   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
