Plain-English summary
Four young Labrador Retrievers experienced rapid heartbeats, known as supraventricular tachycardia (SVT), without any obvious heart disease. This condition was identified through heart monitoring, and two of the dogs showed signs of a specific heart pathway issue. The dogs were treated with antiarrhythmic medications, which helped manage their symptoms effectively. With proper treatment, these young dogs were able to stabilize and improve their heart function.

Abstract
Rapid, clinical supraventricular tachycardia (SVT), without apparent underlying heart disease, was identified in 3 young Labrador Retrievers and 1 Labrador Retriever-type dog. The electrocardiographic characteristics, identification of ventricular preexcitation in 2 dogs, age at onset, response to antiarrhythmic agents, and recent electrophysiologic documentation of a concealed accessory pathway in another young Labrador Retriever suggested orthodromic atrioventricular reciprocating tachycardia as the mechanism of SVT.
