What is automaticity?
The ability of the heart to start and maintain rhythmic activity without the use of
the nervous system
,What is excitability?
ability to respond to outside stimulus
What is repolarization?

What are pacemaker cells?
Cells that send electrical signals through the heart that keep it beating at a steady
rhythm
What is inherent rate?
the normal rate at which a pacemaker cell can produce electrical impulses.
What is conductivity?
ability of the heart cells to move the electrical impulse from cell to cell
What is polarization?
The "resting or ready state" (drawing back for the punch)

of the heart
What is the inherent rate of the SA node?

(intra-atrial tracts) conducts electrical impulses from t he SA node to the left
atrium?
What is the AV Junction?
backup pacemaker cell should the SA Node fail (40-60 BPM)
