How the Heart Works
The amount of force the heart pumps against.
What is afterload.
Heart sounds are produced by what?
What are Valves closing.
The SA node fires at this rate
What is 60-100
An atrial arrhythmia that occurs when the natural cardiac pacemaker site shifts between the SA node, the atria and the AV node.
What is the Wandering Atrial Pacemaker
HR x SV defines what
What is Cardiac Output
The Ventricles pump blood to what two areas?
What are the lungs and the body.
What is the Apex of the heart.
A rhythm that is associated with phases in respiration and the changes in intrathoracic pressure.
What is Sinus Arrhythmia
An atrial rhythm resulting from a single re-entrant circuit.
What is A Flutter
Atrial fibrillation is the result of multiple wavelets of depolarization moving around chaotically.
The percentage of blood your heart pumps in one beat.
What is Ejection fraction (normal 50 -70%)
Blood returns to the heart from the lungs and enters what chamber?
What is the left atrium.
The Leakage of blood backward through the mitral valve into the left atrium.
What is Mitral Regurgitation.
The most common dysrhythmia with acute MI
What is Bradycardia
The half life of Adenosine.
What is < 10 seconds
Term referring to the inability of the ventricles to fill properly.
What is Diastolic Dysfunction
The ability of cells to generate an impulse without being stimulated.
What is Automaticity.
The Five anatomical locations we listen to heart sounds
1)Aortic Valve – 2nd ICS right sternal border (S2)
2)Pulmonic Valve – 2nd ICS left sternal border (S2)
3)Erb’s point- halfway between the apex and the base- 3rd ICS left sternal border
4)Tricuspid Valve – 4th ICS left sternal border (S1)
5)Mitral Valve 5th ICS Mid clavicular line. (S1)
Adenosine works primarily on this node
The normal rate for a Junctional Rhythm.
What is 40-60
The most common cause of right sided heart failure.
What is left sided heart failure.
Flow of depolarization away from a positive electrode result in deflection that is
What is negative
Mitral stenosis is an example of this type of murmur.
What is a Diastolic Murmur.
This medication acts primarily on the SA and AV node conduction.
What is Atropine
A condition characterized by the presence of an abnormal accessory electrical conduction pathway between the atria and the ventricles.
What is Wolf Parkinson White.
The type of heart failure resulting in pulmonary congestion and hypoxia.
What is left sided heart failure.
