Abandonment
|
Termination of the paramedic-patient relationship without assurance that an equal or greater level of care will continue
|
Aberrant Condition
|
Conduction of the electrical impulse through the heart's conduction system in an abnormal fashion
|
Absolute Refractory Period
|
The period of the cardiac cycle when the myocardial cells have not completely repolarized and stimulation will not produce and depolarization whatever
|
Action Potential
|
The stimulation of mycardial cells, as evidenced by a change in the membrane electrical charge, that subsequently spreads across the myocardium
|
Active Transport
|
Movement of a substance through a cell membrane against the osmotic gradient that is, from an area of lesser concentration to an area of greater concentration, opposite to the normal direction of diffusion; requires the use of energy
|
Actual Damages
|
Refers to compensable physical, psychological, or financial harm
|
Addisonian Crisis
|
Form of shock associated with adrenocortical insufficiency and characterized by profound hypotension and electrolyte imbalances
|
Aerobic Metabolism
|
The stage of metabolism requiring the presence of oxygen, in which the breakdown of glucose (in a process called the Krebs or citric acid cycle) yields a high amount of energy
|
Afterload
|
The resistance a contraction of the heart must overcome in order to eject blood; in cardiac physiology, defined as the tension of cardiac muscle during systole (contraction)
