Electrical Conduction System

Across
  1. 4. Two pathways in the heart's electrical system that carry electrical impulses to the right and left ventricles
  2. 7. Contract when they receive an electrical signal from the SA Node
  3. 9. When an electrical current spreads through the heart muscle, causing the ventricles to contract.
  4. 10. When the heart muscle relaxes, or returns to its resting state.
  5. 12. The muscular wall between the right and left ventricles
  6. 13. Known as the pacemaker of the heart
  7. 14. Contract when they receive an electrical signal from the Purkinje Fibers
  8. 15. Embedded in the ventricles causing them to contract
Down
  1. 1. Caused by a disruption in the electrical conduction system
  2. 2. Deliver the signal from the SA node to the AV node
  3. 3. This structure sends the signal from the atria to the ventricles
  4. 5. Ventricular contraction & relaxation begins here
  5. 6. The electrical signal is briefly delayed in this structure
  6. 8. Delivers the signal to the left atrium; Also known as the Bachmann's Bundle
  7. 11. Generated by the SA Node; Travels down the heart's conduction pathway
