Plain-English summary
A 12-year-old Appaloosa gelding that wasn't in shape developed a fast heart rhythm called ventricular tachycardia after a three-day trail ride. He showed signs of stomach pain, not being able to pass food through his intestines, and dehydration. The horse was treated with fluids given through an IV, and during his hospital stay, he developed the fast heart rhythm. Although his potassium levels were normal, he received more fluids and potassium to help. The treatment worked, and the horse's heart rhythm returned to normal.
Abstract
Ventricular tachycardia was diagnosed in a 12-year-old unconditioned Appaloosa gelding after a 3-day trail ride. Initial signs were those of abdominal discomfort, ileus, and dehydration. Medical treatment included IV administration of lactated Ringer's solution. During hospitalization, the horse developed ventricular tachycardia. Serum potassium concentrations were within reference limits; however, assessment of total body potassium stores was not performed. Resolution of the arrhythmia occurred with further fluid treatment and potassium supplementation. Cardiac arrhythmias should be considered in horses in which fluid and electrolyte disturbances are evident after exhaustive exercise.
