Original publication title: Ventricular preexcitation in seven dogs and nine cats.
Plain-English summary
A 6-year-old dog and several cats were brought in for weakness, fainting, or heart failure, and some were found to have a heart condition called ventricular preexcitation. In these cases, fast heart rhythms were noted, and some cats also had heart muscle disease. Treatments included medications like digoxin, propranolol, and quinidine, which helped control the fast heart rhythms and improve heart function. Most pets showed improvement with these treatments, allowing them to feel better and regain strength.

Abstract
Ventricular preexcitation was diagnosed in 6 dogs and 7 cats examined because of weakness, syncope, or congestive heart failure, and as an incidental finding in 1 dog and 2 cats. Reciprocating tachycardias were documented in 8 of the cases. Six of the cats had a pathologic diagnosis of primary cardiomyopathy. Two of the dogs had an associated congenital heart defect. Reciprocating tachycardias were controlled in 4 cases with digoxin, in 2 cases with propranolol, and in 1 case with quinidine. Conduction through the accessory pathway was altered by quinidine (2 cases), digoxin, and propranolol (1 case each), resulting in a lengthened P-R interval and more normal QRS complex configuration.
