The Large Animal Clinic cardiology service marked a significant milestone last month
with the 100th successful cardioversion of a horse suffering from atrial fibrillation — one of the most common performance limiting condition
in horses — using a procedure developed at OVC. Transvenous electrical cardioversion was developed by Drs. Kim McGurrin,Peter Physick-Sheard and
Dan Kenney as a treatment alternative to the drug quinidine. It has become the treatment of choice at OVC due to the higher efficacy,lower risk of adverse effects,
and the ability to quickly return the horse to exercise. The 100th horse was successfully cardioverted on April 27. The
procedure now has a success rate of 99%.
