(217 cards)
A drug acting to relieve pain.
Analgesic
Involuntary muscle jerk
Myoclonus
A movement disorder in which a person’s muscles contract uncontrollably. Twisting movements.
Dystonia
3 components of Cincinnati Stroke Scale
Facial droop, arm drift, slurred speech
The quality or fact of being performed involuntarily or unconsciously
Automaticity
Force of contraction of the heart muscle
Contractility
Cells sending signals to the rest of the heart muscles causing a contraction
Conductivity
Ability of cardiac cells to depolarize and repolarize during the action potential
Excitability
A low concentration of calcium in the blood.
Hypocalcemia
A low concentration of potassium in the blood
Hypokalemia
Inflammation of the myocardium.
Myocarditis
A series of cardiac conditions caused by an abrupt reduction in coronary artery blood flow.
Acute coronary syndromes
Cardiac ischemia that occurs when sudden narrowing or complete occlusion of a coronary artery leads to death (necrosis) of myocardial tissue.
Acute myocardial infarction
Sudden pain that occurs when the oxygen supply to the myocardium is insufficient to meet demand, causing ischemic changes in the tissue.
Angina Pectoris
An outpouching or bulge in the wall of a portion of the aorta, caused by weakening and dilation of the vessel wall.
Aortic aneurysm
The portion of the conduction system of the heart that consists of the AV node and the nonbranching portion of the bundle of His.
AV junction
An accumulation of fat inside a blood vessel that narrows the diameter of the lumen.
Atherosclerosis
A group of cells that slows the electrical impulses from the sinoatrial node before relaying it to the ventricles; located in the floor of the right atrium immediately behind the tricuspid valve and near the opening of the coronary sinus.
AV node
The classic trio of signs associated with cardiac tamponade: narrowed pulse pressure, muffled heart tones, and jugular vein distention
Beck triad
A dysrhythmia in which every other complex is a premature complex, causing a normal–early beat–normal–early beat pattern; can be atrial, junctional, or ventricular.
Bigeminy
On an ECG, leads that contain both a positive and a negative pole: leads I, II, and III
Bipolar leads
Abnormal whooshing sounds indicating turbulent blood flow within a narrowed vessel; usually heard in the carotid arteries.
Bruits
An intraventricular conduction disturbance involving impedance of electrical impulses from the bundle of His to the right or left bundle branch.
bundle branch block (BBB)
class of medication used primarily for the treatment of high blood pressure and heart failure. They work by causing relaxation of blood vessels as well as a decrease in blood volume, which leads to lower blood pressure and decreased oxygen demand from the heart.
ACE inhibitor
