Formula for calculating EF? - CORRECT ANSWER -EF% = (sv/edv) x 100%
Stroke Volume (SV) formula - CORRECT ANSWER -EDV - ESV
What is stroke volume (SV)? - CORRECT ANSWER -
Amount of blood pumped out of each ventricle during a single heart beat.
What is the chiari network? - CORRECT ANSWER -Network of fibers originating from eustachian valve.
Where can the chiari network be found - CORRECT ANSWER -Right atria
What is the most anterior chamber of the heart? - CORRECT ANSWER -Right ventricle
Which pair of intensities has the lowest value? - CORRECT ANSWER -
SATA (spatial average and temporal average)
Where is the Eustachian valve located ? - CORRECT ANSWER -In between the IVC and the right atrium.
,What's another name for the Right Ventricular Outflow Tract (RVOT) ? - CORRECT ANSWER -
Infundibulum

Medial
Posterior
What's the two main layers of the pericardium? - CORRECT ANSWER -
1.) Visceral = lies directly upon external surface of the heart and is commonly referred to as the epicard
ium.
2,) Parietal = or fibrous pericardium is the thick outer sac.
*The pericardial cavity lies between these two layers.
What is the normal pressure for the right ventricle ? - CORRECT ANSWER -25/5 mmHg
What is the normal pressure for the pulmonary artery? - CORRECT ANSWER -25/10 mmHg
What is the normal pressure for the left atrium? - CORRECT ANSWER -10mmHg
What is the normal pressure for the aorta ? - CORRECT ANSWER -120/80 mmHg
What are the two cusps of the mitral valve ? - CORRECT ANSWER -
Anterior (long) and the posterior (short)
When is the left ventricular pressure the lowest? - CORRECT ANSWER -Early diastole
, What is Becks Triad and what does it cause? - CORRECT ANSWER -
AKA cardiac tamponade. Causes an elevated pressure in heart, hypotension and a quiet heart
What are the effects of pulmonary HTN ? - CORRECT ANSWER -Dilated pulmonary artery
Severe TR
RV dilation
What happens to the size of an aneurysm during systole? - CORRECT ANSWER -It increases

What is the normal O2 saturation of the left heart ? - CORRECT ANSWER -98%
What is cardiac output? - CORRECT ANSWER -It is the total amount of blood ejected per minute.
*cardiac output = stroke volume x HR
*normal cardiac output = 4-8 liters/minute
