Cardiac cycle

Across
  1. 2. during this period the ventricles are relaxing
  2. 4. (diagram) looks at the pressure and volumes at the left/right ventricle, aortic pressure during the cardiac cycle
  3. 5. when conduction of the AV node is slowed to allow ventricular filling
  4. 6. effect on heart rate due to increased sympathetic stimulation (or decrease in vagal tone)
  5. 8. fibres that radiate through the walls of the ventricles
  6. 11. during this period the ventricles are contracting
  7. 12. refers to influences on the strength of contraction
  8. 13. formed by hemi channels (a gap junctions) at intercalated disks, allow faster conduction between cardiac cells
  9. 16. (two words without space) the point at which the aortic valve closes and gives a bump in the aortic pressure
  10. 17. method of measuring the difference in potential from the top of the heart to the base
Down
  1. 1. refers to the rate of relaxation of heart
  2. 3. (conduction)allows electrical impulse to travel easier along fibres rather than across
  3. 7. neurotransmitter that decreases chronotropy
  4. 9. effect on heart rate due to increases parasympathetic stimulation
  5. 10. refers to influences on the heart rate
  6. 14. type of SAN cell at the centre node
  7. 15. neurotransmitter that increases chronotropy
