Plain-English summary
A two-year-old Thoroughbred filly was diagnosed with a heart condition called sustained supraventricular tachycardia, which means her heart was beating too fast for an unknown reason. To treat this, she was given a medication called quinidine sulfate, and about 80 minutes after her first dose, her heart returned to a normal rhythm. After about two months of recovery, she was able to go back to training and has been racing successfully since then. Overall, the treatment worked well for her.
Abstract
A case of sustained supraventricular tachycardia of unknown aetiology in a two-year-old Thoroughbred filly is reported. The cardiac dysrhythm was successfully treated by the oral administration of quinidine sulphate. Conversion of the dysrhythm to sinus rhythm occurred approximately 80 min after the initial dose of 5 g of quinidine sulphate. The horse returned to training approximately 2 months after treatment and has since successfully returned to racing.
