CAL: ECG Interpretation with all Correct & 100%
Verified Answers |Guaranteed to Pass
What is the best lead to interepret and why? ✔Correct Answer-Lead II - crosses heart
In what position should a patient be in for an ECG? ✔Correct Answer-Right lateral recumbency
Cats - sternal recumbency
How cna we calculate instantaneuous HR with paper speed of 25mm/s? ✔Correct Answer-HR=
1500/R-R interval(mm)
What if the paper speed is 50mm/s? ✔Correct Answer-Divide R-R interval by 3000 instead
What are the differentials if a QRS complex arises without a P wave? ✔Correct Answer-Ventriclar
depolarisation
Junctional depolarisation
Atrial standstill
Atrial fibrillation
Sinus arrest w/ escape complexes
Wat is the main differential if a P wave arises but not followed by a QRS complex? ✔Correct
Answer-Atrioventricular block
Define 'atrioventricular dissocation' ✔Correct Answer-Seperate ventricular and atrial rhythms
What are 'wandering pacemakers' in dogs? ✔Correct Answer-Normal variation in P-wave
amplitude in dogs
What type of rhythm is atrial fibrillation? ✔Correct Answer-Irregularly irregular
What is the mean electrical axis? ✔Correct Answer-Calculated from the average magnitude of the
deflection of the QRS complex in six leads
Why might the electrical axis be helpful? ✔Correct Answer-Determine if chamber enlargement has
taken place or if there is an abnormality of conduction
What does RA enlargement look like on an ECG? ✔Correct Answer-Tall P-wave (P-pulmonale)
What does LA enlargement look like on ECG? ✔Correct Answer-Wide P-wave, can become notched
or M-shaped
(P-mitrale)
What does LV hypertrophy look like on ECG? ✔Correct Answer-Tall R-waves, wide QRS complexes
Shift of mean electrical axis to the left
What does RV hypertrophy look like on ECG? ✔Correct Answer-Deep S-waves in leads I, II and III
Might be a shift of mean electrical axis to the right
