  1. arrhythmia
    any of several kinds of irregularity or loss of rhythm of the heartbeat
  2. bradycardia
    slow heart rate (<60 beats/min)
  3. fibrillation
    chaotic, irregular contractions of the heart, as in atrial or ventricular fibrillation
  4. flutter
    extremely rapid but regular contractions of the heart, as in atrial or ventricular flutter (typically from 250 to 350 beats/min)
  5. heart block
    an interference with the normal electrical conduction of the heart defined by the location of the block. (AV block)
  6. premature ventricular contraction (PVC)
    a ventricular contraction preceding the normal impulse initiated by the SA node (pacemaker)
  7. tachycardia
    fast heart rate (>100 beats/min)
  8. bacterial endocarditis
    a bacterial inflammation that affects the endocardium or the heart valves.
  9. cardiac tamponade
    compression of the heart produced by the accumulation of fluid in the pericardial sac as results from pericarditis or trauma, causing rupture of a blood vessel within the heart (tampon=a plug)
  10. cardiomyopathy
    a general term for disease of the heart muscle
  11. congestive heart failure (CHF)
    failure of the left ventricle to pump an adequate amount of blood to meet the demands of the body, resulting in a "bottleneck" of congestion in the lungs that may extend to the veins, causing edema in lower portions of the body
  12. coronary artery disease (CAD)
    a condition affecting arteries of the heart that reduces the flow of blood and delivery of oxygen and nutrients to the myocardium-most often caused by atherosclerosis
  13. myocardial infarction (MI)
    heart attack; death of myocardial tissue (infarction) owing to loss of blood flow (ischemia) as a result of an occlusoin (plugging) of a coronary artery-usually caused by atherosclerosis; symptoms include pain in the chest or upper body (shoulders, neck and jaw) shortness of breath, diaphoresis, and nausea.
  14. deep vein thrombosis (DVT)
    formationo of a clot in a deep vein in the body, occuring most often in the femoral and iliac veins
  15. auscultation
    a physical examination method of listening to sounds within the body with the aid of a stethoscope.
  16. bruit
    noise; an abnormal heart sound caused by turbulence within
  17. electrocardiogram (ECG)
    an electrical picture of the heart represented by positive and negative deflections on a graph labeled with the letters P,Q,R S, and T, corresponding to events of the cardiac cycle.
  18. cardiac catheterization
    introduction of a flexible, narrow tube or catheter through a vein or artery into the heart to withdraw samples of blood, measure pressures within the heart chambers or vessels, and inject contrast media for fluoroscopic radiography and cine film imagind of the chambers of the hear and coronary arteries.
  19. stroke volume (SV)
    measurement of the amount of blood ejected from a ventricle in one contraction
  20. caridiac output (CO)
    measurement of the amount of blood ejected from either ventricle of the heart per minute
  21. ejection fraction
    measurement of the volume percentage of left ventricular contents ejected with each contraction
  22. coronary artery bypass graft (CABG)
    grafting of a portion of a blood vessel retrieved form another part of the body to bypass an occluded coronary artery, restoring circulation to mycardial tissue.
  23. defibrillation
    termination of ventricular fibrillation by delivery of an electrical stimulus to the heart.
  24. cardioversion
    termination of tachycardia either by pharmaceutical means or by delivery of electrical energy
  25. pacemaker
    a device used to treat slow heart rates by electrically stimulating the heart to contract
  26. ACE inhibitor
    a druge that suppresses the conversion of angiotensin in the blood by the angiotensin-converting enzyme
  27. antianginal
    a druge that dilates coronary arteries, restoring oxygen to the tissues to relieve the pain of angina pectoris
  28. antiarrhythmic
    a drug that counteracts cardiac arrhythmia
  29. anticoagulant
    a drug that prevents clotting of the blood commonly used in treating thrombophlebitis and myocardial infarction
  30. antihypertensive
    a drug that lowers hypertension
  31. beta blockers
    agents that inhibit responses to sympathetic adrenergic nerve activity causing a slowing of electrical conduction and heart rate and a lowering of the pressue within the walla of the vessels
  32. calcium channel blockers
    agents that inhibit the entry of calcium ions in heart muscle cells causing a slowing of the heart rate, lessening the demand for oxygen and nutrients, and relaxing of the smooth muscle cells of the blood vessels to cause dilation
  33. diuretic
    a druge that increases the secretion of urine
  34. statins
    agents that lower cholesterol in the blood by inhibiting the effect of HMG-CoA reductase
  35. thrombolytic agents
    druges used to dissolve thombi
  36. vasoconstrictor
    a drug that causes narrowing of the blood vessels, decreasing blood flow
  37. vasodialator
    a drug that causes dilation of the blood vessels, increasing blood flow
