A+
Which of the following heart valves are open during ventricular systole? -
🧠ANSWER ✔✔Pulmonic and Aortic
Tricuspid are AV vales and are closed during ventricular systole to prevent
backflow of blood into the atria
The pulmonic and aortic valves, also called semilunar valves, are open
during ventricular systole to allow blood flow to the pulmonary artery from
the right ventricle and blood to the aorta from the left ventricle
Deoxygenated blood enters which heart chamber first after returning from
systemic circulation? - 🧠ANSWER ✔✔Right atrium
,During what phase does the heart muscle receive its blood supply? -
🧠ANSWER ✔✔In Diastole
What is the function of chordae tendineae? - 🧠ANSWER ✔✔To prevent
valve failure/prolapse
Which of the following are the AtrioVentricular valves (AV Valves)? -
🧠ANSWER ✔✔Tricuspid and bicuspid valves
You are assessing a patient that has ST segment elevation in leads II, III,
and aVf. Where is the location of the MI? - 🧠ANSWER ✔✔Inferior wall or
Right sided
You are responding to an emergency department to transport a 56 year old
male who is experiencing abdominal discomfort and nausea. The sending
facility has performed a 12-lead EKG and hands you a copy before MD
interpretation.
You note the following:
Inverted T waves on V1, V2, V3
Normal appearance in all other leads
, Inverted QRS complex in aVr.
What is your interpretation of this 12 lead EKG? - 🧠ANSWER ✔✔Septal
wall myocardial infarction
Inverted T waves are suggestive of ischemia in appropriate clinical setting.
Ischemia can be due to an acute coronary syndrome caused by rupture of
atherosclerotic plaque or due to increasing oxygen demand or decreasing
oxygen supply, such as anemia or sepsis.
Your colleague is confused about a LBBB vs a RBBB
They respect you as a critical care provider and ask your opinion.
They show you a 12 lead EKG and asks you to explain it to them.
What lead(s) would you direct him to focus on to make this determination? -
🧠ANSWER ✔✔V1 and V6
