  3. Angiocardiography
    An x-ray procedure that permits visualization of the vascular tree of the heart through the intravascular injection of radiopaque contrast medium
  4. apical-radial pulse

    abnormal accumulation of lipid deposits and fibrous tissue within arterial walls and the lumen.
  7. Cardiac Output
    Amount of blood discharged from the left or right ventricle per minute
  8. Cardiovascular
    Pertains to the heart and blood vessels
  9. Chemoreceptors
    Chemoreceptors sense organs or sensory nerve endings which are stimulated by a chemical substance
  10. Cholesterol
    A sterol widely distributed in animals tissues and occurring in the yolk of eggs various oils, fats and nerve tissue of the brain and spinal cord
  11. Clubbed fingers
    Rounding of ends and swelling of fingers in children with congenital heart disease and in older children and adults with long-standing pulmonary disease.
  12. coronary occlusion
    closing off of a coronary artery
  13. cor pulmonale
    Acute heart strain or chronic right ventricular hypertrophy with or without heart failure resulting from disease states which affect the function and structure of the lungs and cause pulmonary hypertension
  14. CK-MB
    Creatinine kinase. Enzyme located primarily in the heart muscle. Elevations highly indicative of an MI
  15. Dysrhythmias
    disorders of formation or conduction of the electrical impulse within the heart.
  16. digitalizing dose
    subjection of an organism to the action of digitalis
  17. Echocardiogram
    use of ultrasound to assess both the structures and motions within the heart. A small transducer is placed on anterior chest and moved in various direction to visualize specific cardiac areas

    A congentail anomaly in which the fetal ductus arteriosus
  26. Pulmonary edema
    effusion of serous fluid into air vesicles and into interstitial tissue of lungs
  27. Sedimentation rate (sed rate)
    Laboratory test of speed at which erythrocytes settle when an anticoagulant is added to blood
  28. Tetralogy of Fallot
    A congenital condition characterized by defect in the interventricular septum, stenosis of the pulmonary artery overriding of the aorta and hyper trophy of the right ventricle

  30. Thrombosis
    formation of a blood clot
  31. Valves
    Cusps or flaps of the heart lining that close as the heart chambers fills up with blood thus keeping flowing in one direction
