An 82-lb (37 kg) 8-year-old MN German Shepherd mix is being evaluated
for a 2 month history of decreased exercise tolerance. The client reports
that the dog had two episodes of profound weakness on walks during the
past week. The dog seems comfortable at home but his "heart is always
racing." Two years ago the dog was diagnosed by another vet with
hypothyroidism and prescribed oral levothyroxine 0.8 mg twice daily.
Dosage was reevaluated one month after initiation and was determined to
be appropriate. Appetite, urination, and bowel movements are normal. BCS
is 6/9. Temp 101.2 F and HR 180 bpm. The dog is panting. Pulse deficits
are occuring 3-5x/min. No other abnormalities are noted. CBC, serum
chemistry, and urinalysis are WNL. Which of the following is the most likely
cause of episodic weakness in this dog?
A) Decreased cardiac output
B) Electrolyte imbalance
