Show Answers:

  1. cardiac tamponade
    acute compression of the heart due to the accumulation of fluid within the pericardial cavity
  2. coronary occulation
    blockage of an artery that supplies the heart, often due to atherosclerosis
  3. cor pulmonale
    chronic enlargement of the right ventrile that results from congestion within the pulmonary circulation
  4. coarctation of the aorta
    congenital disease in qhich the aorta is narrowed
  5. fibrilation
    uncoordinated, rapid contraction of the ventricles or atria
  6. myocardial infraction
    acute episode in which the myocardium is deprived of blood flow leading to tissue death
  7. patent ductus arteriosus
    • Condiction characterized by an opening between the pulmonary artery and the aorta, allowing blood to pass across
    • The connecting channels that is a normal part of the fetal circulation before birth fails to close and thereby remains open
  8. tetralogy of Fallot
    • four congenital defects associated with the heart combined- pulmonary valve stenosis, ventricular septal defect, incorrect position of the aorta, and right ventricular hypertrophy.
    • As a result, the pulmonary circuit is bypassed
  9. Thromboangiitis Obliterans
    vascular inflammatory disease that usuallyy affects the lower extremities
  10. varicosis
    a condition of an abnormaly dialted vein
  11. ventriular septal defect
    an opening iin the septum that separates the right ventricle from the left ventricle, allowing blood to pass between them
  12. positron emission tomography scan
    procedure that provides blood flow images using PET scan techniques with radioacctive isotope labeling
  13. sphygmomanometry
    procedure that measures arterial blood pressure using a device called a sphygmomanometer- which consists of an arm cuff and air ressure pump with a pressure gauge
  14. myocardial radionuclide perfusion scan
    test in which blood flow to cardiac cells is monitored following injection of an isotope. The test may be performed while the patient is under stress or at rest
  15. Holter ambulatory monitor
    portable electrovardiograph worn by the patient, records electrical activity of the heart of 24 hour periods, proving useful in detecting periodic or transient abnormalities
  16. endarterectomy
    surgical removal of a fatty plaque or a blood clot from the interior of an artery
  17. Doppler Sonography
    ultrasound procedure that evaluates blood flow through a blood vessel
  18. coronary stent
    a metalloc scaffold that is implanted in a coronary artery to prevent closure of an artery after angioplasty or atherectomy
  19. cardiopulmonary resuscitation
    • emergency response procedure that includes artificial ventilation and external heart massage in an effrt to resuscitatie, or revive, the patient
    • CPR
  20. cardiac catheterization
    • procedure which involves inserting a flexible catheter into a brachial or femoral artery and threading it into the heart.
    • It is used to obtain blood samples, pressures and determine the presence and degree of coronary artery disease
