Electrical Activity in the Heart Exit Ticket

The AV Node is the natural pace maker of the heart and next to the superior vena cava

• true

• false

Where does electrical activity in the heart start?

• Purkinje Fibers

• AV node

• Bundle of HIS

• SA node

(a)   is when the heart rate is moving to fast(above 100 bpm)

Match the definition to the word: this node is a small pause that allows the ventricles to fill with blood

• SA node

• Bundle of HIS

• bicuspid valve

• AV node

Match the word to the definition: works with the Purkinje Fibers to ensure both ventricles contract together

• Bicuspid Valve

• Bundle of HIS

• Aortic Valve

• Bundle of Purkinje

In order for both ventricles to contract at the same time what two electrical conductions are necessary?

• Purkinje Fibers

• AV node

• Bundle of HIS

• SA node

A normla heart rate is between what numbers?

(a)  

match the word to the definition: When the heart rate is moving too fast

• tachycardia

• systolic

• your heart is moving too fast

• bradycardia

What is the measurement used for blood pressure

• millimeters of minutes

• millimeters per beat

• millimeters of mercury

• millimeters of methane

What is the correct order for electrical activity in the heart?

• Purkinje fibers --> Bundle of HIS --> AV node --> SA node

• Bundle of HIS --> AV node --> SA node --> purkinje fibers

• Av node --> SA node --> Purkinje Fibers --> Bundle of HIS

• SA node → AV node → Bundle of HIS --> Purkinje Fibers
