Amnesia - ✔✔ Failure to remember events related to surgery
Analgesia - ✔✔ Insensitivity to pain
Anaphylaxis - ✔✔ A severe allergic reaction marked by any of several severe responses, including skin reactions, smooth muscle cramping, urinary incontinence, construction of bronchioles, respiratory difficulty, and cardiovascular collapse
Anemia - ✔✔ A reduction in the number of red blood cells in the bloodstream
Angina pectoris - ✔✔ Pain in the chest, with a feeling of suffocation, usually due to deficiency of blood supply to the myocardium
Antecubital - ✔✔ Situated in front of the elbow
Antecubital fossa - ✔✔ The depression between the forearm and the upper arm that is literally "in front of the elbow"

Aorta - ✔✔ The main trunk (a very large artery) from which the arterial system proceeds
Apnea - ✔✔ Absence or cessation of breathing
Arrest rhythms - ✔✔ Cardiac rhythms in which there is cardiac arrest. Some arrest rhythms such as pulseless ventricular tachycardia are accompanied by a rhythm display, but there is no contraction
Arrhythmia - ✔✔ Any variation from the normal rhythm of the heartbeat
Arteriole - ✔✔ Any of the very small arterial branches located at the end of an artery (furthest from the heart)
Artery - ✔✔ A vessel that varies blood away from the heart to other parts of the body
Ascites - ✔✔ Accumulation of the serous fluid in the abdominal cavity
Asystole - ✔✔ Cardiac arrest in which there is no rhythm display and no contraction
Ataractics - ✔✔ Pharmacologic agents that produce a tranquilizing effect
Atherosclerosis - ✔✔ A disease of the arteries characterized by the deposition of plaques of fatty material on their inner walls
Atrial fibrillation - ✔✔ Atrial arrhythmia characterized by rapid randomized contractions of the atrial myocardium, causing a totally irregular and often rapid ventricular rate
Atrial flutter - ✔✔ A condition of cardiac arrhythmia in which the atrial contractions are rapid (200 to 320 per minute)
Atrial (supraventricular) rhythms - ✔✔ Dysrythmias in which the pacemaker is in the atria above the level of the ventricles (supraventricular) area
Atrial Tachycardia - ✔✔ Rapid heartbeat originating from the atria
Atrioventricular block (AV block) - ✔✔ A cardiac conduction defect in which the impulse generated by the SA node is partially or completely blocked in the area of the AV nose
Atrioventricular node - ✔✔ A microscopic collection of heart muscle fibers involved in the electrical activity of the heart
Atrium (plural: atria) - ✔✔ An upper chamber of the heart; atria also exist in other parts of the body
Automaticity - ✔✔ The condition of being automatic
Autonomic nervous system - ✔✔ A portion of the nervous system concerned with regulation of the activity of cardiac muscle, smooth muscle, and glands
Balanced anesthesia - ✔✔ Anesthesia that relies on the use of several agents together, capitalizing on the best aspects of each agent, but using each at a smaller dose than would be required if it were used alone
Barbiturates - ✔✔ A group of pharmacologic agents that have sedative properties and produce amnesia and a hypnotic effect (eg, thiopental sodium, brevital)
Baroreceptor - ✔✔ A sensory nerve ending that is stimulated by changes in pressure, as those in the walls of blood vessels [Show Less]
