Across
  1. 4. the sound of the semilunar valves closing
  2. 7. what is the valve separating the left atrium and ventricle
  3. 9. the sodium channels that will close during an action potential
  4. 11. the low pressure chamber of the heart
  5. 13. what plane of the heart does the ECG provide information for
  6. 14. the part of the cardiac cycle that have the phases; isovolumic contraction and ventricular ejection
  7. 16. cardiac muscle are incapable of having _____ of an action potential
  8. 17. turbulent flow within the heart
  9. 22. what side of the heart does the wigger's diagram show
  10. 23. the sound of the AV valves closing
  11. 27. this factor that affects the stroke volume is the end-diastolic volume
  12. 28. what is the valve separating the right atrium and ventricle
  13. 29. when the heart rate increases what happens to the duration of the cardiac cycle
  14. 30. what occurs between the first and second heart sounds
  15. 33. section of the wiggers diagram that shows the normal heart sounds
  16. 36. is typically 60% and is calculated by stroke volume/end-diastolic volume
  17. 37. the section between the P wave and the beginning of the Q (does not include the pwave)
  18. 38. which ANS pathway predominates in the heart
  19. 40. this is the intrinsic relationship between the end-diastolic volume and stroke volume (3-words)
Down
  1. 1. the ecg wave(s) that represent ventricular depolarization
  2. 2. this correlates with the plateau of the ventricular AP
  3. 3. parasympathetic stimulation will do what to the PR interval
  4. 4. relax or filling
  5. 5. parasympathetic fibers will send signals to this receptor in the heart M2 and M3
  6. 6. this factor that affects the stroke volume is termed the ANREP effect
  7. 8. the part of the cardiac cycle that has phases: atrial systole, isovolumic relaxation, rapid influx and diastasis (2words)
  8. 10. total volume of blood ejected by the heart PER MINUTE (2 words)
  9. 12. total volume of blood ejected PER BEAT (2 words)
  10. 15. this node/fibers are responsible for delaying the conduction impulse from the right ventricle allowing time for the atrium to empty the final amount of blood into the ventricle
  11. 18. which side of the heart pumps blood to the lungs
  12. 19. the ecg wave(s)that represents ventricular repolarization
  13. 20. this adrengic receptor is found in the SA/AV node and myocardial cells and will increase HR, stroke volume and cardiac output (2 words)
  14. 21. this factor that affects the stroke volume refers to the pumping ability of a ventricle
  15. 24. this adrengic receptor is found in the arterioles and will cause vasodilation (2 words)
  16. 25. the term for the heart valves opening less than normal
  17. 26. the abnormal heart rate/beat
  18. 27. the ecg wave(s) that represents atrial depolarization
  19. 31. the shape in which the prongs are placed in an ecg
