Wednesday
Review and know the main structures of the heart.
What are the wall thicknesses (mm) of the different chambers of the heart?
What is a pressure gradient and how does it relate to blood flow through the heart.
Know the blood flow through the pulmonary and systemic circuit.
How much blood passes from the atrial to the ventricles (in %) before the atria contract. What is another name for the atrial contraction? (answer: atrial 'kick')
Explain and describe the cardiac cycle. There are THREE specific phases. What are they?
What is the systolic pressure in the pulmonary and systemic circuit?
Who is William Harvey? Who is Augustus Waller? Who is Willem Einthoven?
Explain in detail the cardiac conduction system. Starting from the SA node, make sure you can draw and explain the electrical conduction pathway to the purkinjie fibers. What is another name for the interatrial tracts pathway? What is Bachmann's bundle?

Friday (Cardiovascular physiology review; may carry over to Monday)
Explain depolarization and repolarization.
What is the difference in efflux and influx?
Note the difference and similarities in skeletal muscle motor unit (nerve, neuromuscular junction, muscle cell) activation and cardiac muscle (autorhythmic cell, gap junction, cardiac contractile cell) activation.
Name and Explain in DETAIL all Phases of Depolarization and Repolarization of a cardiac contractile cell. Make sure you state the ions associated with each Phase (differentiate the slow and fast sodium channels).
What is the difference in autorhytmic and contractile cells.
What are the two main types of heart cells we are discussing in class?
A vector has direction and amplitude. Explain why a EKG tracing is a vector?
The SA node’s automaticity is referred to as an _____ rhythm?
As the cell deplorarizes, is the inside of the cell becoming more positive or negative?
As depolarization advances TOWARDS a positive electrode, which way is the deflection on the tracing?
As depolarization advances TOWARDS a negative electrode, which way is the deflection on the tracing?
As depolarization advances PERPENDICULAR TO A lead, which way is the deflection on the tracing?
What does biphasic mean with an EKG deflection?
Describe an EKG tracing and explain what is happening electrically and mechanically (i.e, P wave is atrial depolarization, QRS is....etc).
Identify the deflections (P, Q, R, S, T) on an EKG tracing.
