Cardiovascular dz of other species Flashcards
1
Q
How does application/interpretation of ECG differ between species?
A
Atria- then ventricles- then repolarisation
P- then QRS- then T
some species have an SV wave due to depolarisation of the sinus venosus which precedes depolarisation of the atria = additional waves
small species = small intervals + viceversa
2
Q
What are the challenges of echocardiography between species?
A
High heart rates need high frame rate
small hearts need high frquency transducers (good resolution)
large hearts need low frequency transducers (good penetration/depth of field)
adequate imaging windows
3
Q
What are the limitations of radiography between species?
A
patient size: ability to penetrate the thorax
species anatomy
non mammals: air sacs, relationship of heart to lungs
