Echocardiogram Flashcards
What frequency do you need for a cat/small dog, medium dog and large dog?
- Cats/Small dog
◦ 7.5MHz - Medium dogs
◦ 5MHz - Large dogs
◦ 2.5-3.5MHz - The larger the dog, the deeper the chest, the lower the frequency needs to be.
What is gain?
Helps adjust the overall brightness of the image.
Gain is the amplification of the ultrasound signals your transducer records. Each echo gets turned into a lighter or darker (depending on the echogenicity) pixel on your machine’s screen, and gain dictates how much each echo is amplified.

How do you get a right parasternal long axis view?
Thumb on ‘thumb mark’
Palpate apex beat.
Place probe on dog with thumb towards you
How do you get a right parasternal short axis view?
From RPLA 4 chamber view turn thumb to bum and turn the probe 90 degrees.
Tilt probe +/- slide probe up chest wall as necessary.
Which views are these?
Right parasternal short axis (RPSA) views
Which view is this?
Right parasternal short axis view LV @ pap mm level
Right ventricle small at the top.
Left ventricle dominating in the middle.
PAP = Elevated pulmonary pressure (PAP) -> attach doppler in this view
MM = measure left ventricle

Right ventricle short on top.
Which view is this?
Right parasternal short axis @ chorda tendinae -> fish mouth
