DEPOLARIZATION Movement of ions (Na+, Ca+, K+) across cell
membrane causing inside of cell to become more
positive, electrical conduction results in
contraction. Na+ channels open. Positive inside,
negative outside.
REPOLARIZATION movement of ions across cell membrane where
inside of cell is restored to its negative charge.
Sodium channels close. Potassium channels open.
Active transport by sodium-potassium pump
DEPORIZATION ELECTRICAL
CONTRACTION IS MECHANICAL. CONTRACTION FOLLOWS
DEPOLARIZATION.
WHAT OCCUR FIRST? ELECTRICAL ELECTRICAL CONDUCTION
CONDUCTION, OR MECHANICAL
CONTRACTION?

P WAVE ATRIAL DEPOLARIZATION
QRS VENTRICAL DEPOLARIZATION
T WAVE ventricular repolarization
REFRACTORY PERIOD the period of resistance to stimulation, cardiac
cells unable to respond to stimulus
relative refractory period cardiac cells have repolarized enough to respond
to strong stimulus
automaticity Ability of pacemaker cells to spontaneously initiate
an electrical impulse, SA node, AV junction, and
Purkinje fibers
excitability ability to respond to stimuli
conductivity Ability to receive an electrical stimulus and
conduct that impulse to adjacent cells - all cardiac
cells possess this.
contraction Cardiac cells shorten, causing muscular
contraction in response to an electrical stimulus
SA node Sino-atrial node; the pace-maker of the heart;
where the impulse conduction of the heart usually
starts; located in the top of the right atrium. 60-100
bpm
