How would you angle to see the coronary sinus in the apical 4 view? - ANSWER
Angle posterior
Why is it vital to know the location of the coronary sinus and descending aorta?
They serve as key cues for distinguishing between pericardial and pleural effusions.
What causes the coronary sinus to become dilated? Due to increased pressure in the
RA or increased flow into the coronary sinus as in some congenital abnormalities.
Name the three main coronary arteries. Where do they sit on the surface of the
heart? - ANSWER - Right: emerges from the right aortic root sinus, follows the
right atrioventricular junction, and descends via the posterior interventricular
groove.
- Left anterior descending, following the anterior interventricular groove.
- circumflex: runs via the left atrioventricular junction.
,Identify the cardiac walls supplied by each of the coronary arteries. Right coronary:
inferior, inferoseptal, right ventricular apex, and right ventricular free wall
Left anterior descending: anterior, anteroseptal, and left ventricular apex.
Circumflex: anterolateral and inferolateral
While examining a 43-year-old man with a previous MI, you note that the anterior
heart wall is dynamic. Which coronary artery was most likely to be implicated in
the infarction? - ANSWER Left anterior descending coronary artery.
What are the typical systolic and diastolic pressures in the four heart chambers and
great vessels? When is the LV pressure at its lowest? - Answer: RA = 6 mmHg.
RV equals 25/5 mmHg
Pulmonary artery: 25/10 mmHg.
LA equals 10 mmHg.
LV = 120/7 mmHg.
Aortic: 120/80 mmHg
LV pressure is lowest in the EARLY DIASTOLE shortly after the MV opens.
What is the typical mean pulmonary artery wedge pressure? - ANSWER: 10
mmHg
, Which two-dimensional view would you use to see the front wall of the left
ventricular? - ANSWER Apical 2 chambers
Which two-dimensional image would you use to visualize the anterolateral wall of
the left ventricular? - ANSWER Apical 4 chambers
At what point on the electrocardiogram does the MV typically close? - ANSWER
60 milliseconds after the start of the QRS complex, or roughly halfway through the
QRS complex.
On the electrocardiogram, at what point does the AV typically open? - ANSWER
The end of the QRS complex.
What is diastasis? - ANSWER Denotes the middle of diastole, which occurs
between early, rapid ventricle filling and the commencement of atrial contraction.
How much of the ventricular filling occurs during diastole's passive phase? -
ANSWER: 79%
Name the four stages of diastole. - ANSWER: isovolumic relaxation time.
- Early Filling
- Diastasis
- Atrial contraction
