Original
What is stroke volume?
The amount of blood ejected from the left ventricle during systole (ventricular
contraction).
What are signs and symptoms of decreased Cardiac Output?
Low BP
Pale
Clammy
Hypoxia
Decreased LOC
Urinary Output
Chest Pain
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 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)
What is depolarization?
the discharge state (the actual punch)
What is repolarization?
Recovery state (drawing back after the punch)
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 the SA Node?
pacemaker of the heart
What is the inherent rate of the SA node?
60-100
what is Bachmann's bundle?
(intra-atrial tracts) conducts electrical impulses from t he SA node to the left
atrium?
What are internodal tracts?
conducts electrical impulses from the SA node to the AV node.
What is the AV node (atrioventricular)?
causes a brief delay in the conduction process allowing the atria to contract
What is the AV Junction?
backup pacemaker cell should the SA Node fail (40-60 BPM)
what is the bundle of HIS?
sends electrical impulse through the left and right ventricle.
What is the Purkinje fibers?
backup pacemaker if the SA and the AV node should fail (20-40 BPM) it may not be
able to adequately profuse the brain and other vital organs.
What is the correct order of the conduction system?
SA Node
Bachmann's Bundle
Internodal Tracts
AV Node
AV Junction
Bundle of His
Purkinje Fibers
What is the pacemaker rule?
the fastest inherent rate will control the heart (SA Node, AV Junctions, Purkinje
Fibers)
What is the escape rhythm?
when the normal pacemaker (SA Node) fails or slows down, the site with the next
fastest rate will pick up (AV Junction, Purkinje fibers)
What is irritability of the heart?
when internal damage of the heart is present due to MI, hypoxic state, trauma, or
electrolyte imbalances.
What are premature beats?
both excitability and irritability are the main cause of premature beats and it occurs
before the next expected beat?
What is the sympathetic system?
speeds everything up, fight or flight
What is the parasympathetic system?
slows everything down (vagus nerve)
What is pulseless electrical activity (PEA)?
a rhythm that should produce a pulse but doesn't
What is the mechanical activity of the heart?
BP and pulses, electrical activity can happen without mechanical activity
