Questions and Answers

  • 2. 
    What series of electrical events occur within the heart to cause the Atria to contract?

  • 7. 
    What series of electrical events occur within the heart that cause the Ventricle's to contract?
    • A. 

      Action potential starts at the 'AV node' and travels to the 'SA node' which caused the atrium to contract, the action potential then travels down the 'bundle of his' and onto the 'perjinke fibres' causing the Ventricle's to contract.

    • B. 

      Action potential starts at the 'SA node' and travels to the 'AV node' which caused the atrium to contract, the action potential then travels down the 'bundle of his' and onto the 'perjinke fibres' causing the Ventricle's to contract.

    • C. 

      Action potential starts at the 'SA node' and travels to the 'AV node' which caused the atrium to contract, the action potential then travels down the 'bundle of his', down the "left and right branches' and onto the 'perjinke fibres' causing the Ventricle's to contract.
