Electrophysiogogic terms

loading
Blood pumped by the heart over the period of 60 seconds?
CARDIAC OUTPUT
The process of passing a current through a fibrillating heart to depolarize the cells and allow them to re-polarize uniformly, thus restoring organized, coordinated contractions?
DEFIBRILLATION
When stimulated has rhythm?
RHYTHMICITY
Ability to spontaneously generate and discharge electrical impulses?
AUTOMATICITY
Ability of a cell to shorten or lengthen its muscle fibers?
CONTRACTILITY
movement or propagation of electrical impulses from cell to cell through tissue?
CONDUCTIVITY
Ability to respond to an electrical impulse?
EXCITABILITY
Involved in control of negative functions, mediated largely by the vagus nerve.
PARASYMPATHETIC NERVOUS SYSTEM
Causes blood vessels to constrict, increases heart rate, prepares body to respond to stress
SYMPATHETIC NERVOUS SYSTEM
Movement of transmembrane potential in a negative direction to reestablish a polarized state/
REPOLARIZATION
Condition in which ions of opposite charges are separated by a semipermeable ll membrane' resting state?
POLARIZATION
Resting phase of the cell membrane; no electrical activity will be present on the ECG tracing?
ISOELECTRIC
Movement of transmembrane potential in a positive direction, resulting in contraction?
DEPOLARIZATION
Early phase of repolarization when no stimulus, no matter how strong, can generate a response?
ABSOLUTE REFRACTORY
