Disorders
What is the term for a heartrate above 100bpm?
What is the first step in the conduction pathway?
SA node fires
What is the name for the layer of the heart that is responsible for beating?
myocardium
Which chambers sit inferior to the AV valves?
ventricles
If we wanted to see how the conduction pathway is firing, what test would we use?
EKG/ECG
What is the alternative name for a heart attack?
myocardial infarction
Which part of the conduction systole is responsible for atrial systole?
AV node
The left side of the heart is responsible for which circuit?
Bonus: right side?
systemic
Bonus: pulmonary
What kind of blood should be in the right atrium?
deoxygenated
If we wanted to see the heart beating in real time, but NOT undergo a surgical procedure, we might use:
Echocardiogram (heart ultrasound)
Which structures are associated with murmurs?
T/F: An EKG tracks the heart's beats.
F; it records to electric impulses fired by the conduction system
Name the semilunar valves.
pulmonary and aortic
What type of blood should be in the pulmonary veins?
oxygenated
If we wanted to perform auscultation of the heart, what tool would we use?
stethoscope
How is congestive heart failure classified?
Stage 1-4 (with 4 being the most severe)
What events are occurring during atrial systole?
atria contract
Why is the left ventricular wall thicker than the right?
the left is responsible for pumping blood through the systemic circuit whereas the right is only responsible for the pulmonary circuit

A patient presents with history of a persistent sore throat, and now reports "quickly fatiguing and feeling like they have a fluttering chest". What might you suspect is the issue, and what test would you order to see?
Rheumatic heart disease, Echo to view damaged valves and potentially use a stethoscope to listen for damage-induced murmurs.
