If a patient is younger (<40yo) with anomolous coronaries, what type of symptoms may
be seen? - 1. DOE
2. Exercise-induced angina
How much of a cardiac cycle is accounted for by diastole? - 2/3
What is another term for apical 2 chamber? - Vertical long axis (VLA)
What is another term for apical 4 chamber? - Horizontal long axis (HLA)
The best images of the ascending aorta are often obtained from which transducer
window? - Suprasternal
What cardiac pathology is associated with bicuspid aortic valves? - Aortic coarctation
What are two ways of describing where aortic coarctations most often occur? - 1. After
the take-off of the left subclavian artery
2. Within the aortic isthmus
Which pulmonary veins are seen in the Apical 4 chamber? - Lower pulmonary veins.
Which pulmonary veins are seen in the Apical 5 chamber? - Upper pulmonary veins.
From the apical 4 chamber view, how do you rotate the transducer to obtain the Apical
LAX? - Counterclockwise 120 degrees
Where is the coronary sinus located? - Posterior AV groove.
To visualize the coronary sinus in the Apical 4 chamber view you should tilt the
transducer: - Posterior
Which valve sits at the opening of the coronary sinus? - Thebesian

What is the absolute refractory state? - The period when muscle cells cannot become
excitable.
What does the P wave represent? - Atrial systole.
What does the PRI represent? - Atrial to ventricular depolarization.
What does the T wave represent? - Ventricular diastole (repolarization).
What is the normal duration for the QRS complex? - <0.12sec
What 4 things increase with an increased preload? - 1. Volume
2. Contractility
3. Myocardial fiber length
4. Tension
What is afterload? - 1. The load (volume) exerted on the ventricle at end diastole.
2. The resistance against which the ventricle must pump.
What type of chamber changes are found with chronic increased preload? - Dilation
What type of chamber changes are found with chronic increased afterload? -
Hypertrophy
How does acute AI affect the contractility of the LV? - LV becomes hypercontractile.
Equation: Stroke volume - EDV-ESV
Equation: Ejection fraction - (SV/EDV) x 100
Normal value: Stroke volume - 70-110mL
Normal value: Ejection fraction - >55%
Equation: Cardiac output (angiographic) - SV x HR
Normal value: Cardiac output - 4-8L/min
