  1. afterload
    a measure of the vascular resistance that the left ventricle must overcome in order to eject blood during contraction
  2. cardiac glycoside
    drug obtained from plants of the genus digitalis
  3. cardiac output (CO)
    the amount of blood pumped per minute by the heart
  4. chronic heart failure (CHF)
    condition in which the heart is unable to pump sufficient blood to the tissues of the body
  5. digitalization
    method of dosage with cardiac glycosides that rapidly produces effective drug levels
  6. ectopic beat
    extra heartbeat, a type of cardiac arrhythmia
  7. hypercalcemia
    high serum calcium
  8. hyperkalemia
    high serum potassium
  9. hypokalemia
    low serum potassium
  10. maintenance dose
    daily dosage of cardiac glycoside that maintains effective drug levels in the blood
  11. Na/K adenosine triphosphatase (Na/K ATPase)
    enzyme that energizes the sodium/potassium pump and is inhibited by cardiac glycosides
  12. preload
    refers to venous return, the amount of blood returning to the heart that must be pumped
  13. antiarrhythmic drug
    drug used to restore normal cardiac rhythm
  14. arrhythmia
    disorder of cardiac conduction and electrical impulse formation
  15. cinchonism
    quinidine toxicity, which is characterized by ringing in the ears (tinnitus), dizziness, and headache
  16. ectopic focus
    area of the heart from which abnormal impulses originate
  17. premature atrial contraction (PAC)
    premature contraction of the atria, usually caused by an ectopic focus.
  18. premature ventricular contraction (PVC)
    premature contraction of the ventricles, usually caused by an ectopic focus
  19. proarrhythmia
    an arrhythmia caused by administration of an antiarrhythmic drug
  20. supraventricular arrhythmia
    arrhythmia that originates above the AV node in the atria
  21. torsade de pointes
    a type of proarrhythmia that causes ventricular tachycardia and fainting
  22. ventricular fibrillation
    the most serious arrhythmia; usually a terminal event where ventricular contractions are no longer able to effectively pump blood
  23. angina pectoris
    chest pain due to decreased blood flow (ischemia) to the heart
  24. atherosclerosis
    fatty degeneration of arteries due to accumulation of cholesterol plaques
  25. coronary artery
    artery that supplies blood flow to the heart
  26. coronary artery disease (CAD)
    condition due to atherosclerosis and insufficient blood flow to the heart
  27. exertional angina
    angina pectoris caused by increased physical exertion
  28. ischemia
    insufficient blood flow to a tissue
  29. variant or Prinzmetal angina
    angina pectoris caused by vasospasm of the coronary arteries
  30. aldosterone
    hormone released from adrenal cortex that causes the retention of sodium from the kidneys.
  31. angiotensin-converting enzyme inhibitor (ACEI)
    drug that inhibits the enzymatic conversion of angiotensin I to angiotensin II
  32. angiotensin receptor blocker (ARB)
    drug that blocks receptors for angiotensin II
  33. angiotensin II
    potent vasoconstrictor that also stimulates release of aldosterone and antidiuertic hormone
  34. antidiuretic hormone (ADH)
    hormone from the posterior pituitary gland that causes retention of water from the kidneys
  35. blood pressure (BP)
    the pressure of the blood within the arteries; depends primarily on the cardiac output and the peripheral resistance
  36. cardiac output (CO)
    the amount of blood pumped per minute by the heart
  37. essential hypertension
    major form of hypertension for which the cause is unknown
  38. heart rate (HR)
    number of heartbeats per minute
  39. hypertension
    abnormally high blood pressure
  40. malignant hypertension
    hypertensive crisis associated with inflammation and vascular damage
  41. peripheral resistance (PR)
    resistance generated by the flow of blood through the arteries
  42. renin
    enzyme released by kidneys that converts angiotensinogen into angiotensin I
  43. secondary hypertension
    form of hypertension in which the cause is known
  44. stroke volume (SV)
    amount of blood pumped per heartbeat
