Topic:Clinical Findings
Clinical findings in horses encompass a range of observable signs and symptoms identified during veterinary examinations that contribute to diagnosing and managing equine health conditions. These findings can include physical observations, such as changes in behavior, posture, or gait, as well as physiological measurements like heart rate, respiratory rate, and temperature. Diagnostics may also involve laboratory tests, imaging, and other diagnostic procedures to assess organ function and detect abnormalities. Recognizing and interpreting clinical findings are essential components of veterinary practice, aiding in the identification of diseases, monitoring treatment progress, and guiding therapeutic interventions. This page brings together peer-reviewed research studies and scholarly articles that explore the methodologies, interpretations, and implications of clinical findings in the context of equine health care.

The purpose of this study was to determine the value of ABE as a diagnostic tool for horses treated for gastrointestinal disease. Unassigned: This retrospective case series evaluated horses admitted for acute gastrointestinal disease over a 5-year period (2019-2024). Signalment, physical exa...
Emergence of a new alveolar dental element after extraction of a molar tooth in a horse. A 2-year-old mixed-breed mare was examined at the property due to swelling and fistula on the right mandible. Oral examination and radiographs revealed the presence of an apical abscess involving the 410 tooth. The tooth was extracted entirely and confirmed radiographically. One year later, the owner reported a reoccurrence of clinical signs. A new radiographic evaluation revealed a radiopaque area in the alveolar socket of the 410 tooth filled with spongy-looking bone. An extraoral approach to the alveolar socket was performed, and the content removed had the appearance of a dental element.

Orthodromic Atrioventricular Reentry Bradycardia and Tachycardia Caused by an Accessory Pathway in Horses. Accessory pathways (APs) are muscular bundles directly connecting the atria and ventricles, bypassing the atrioventricular (AV) node-His-Purkinje system. Anterograde conduction along the AP results in ventricular preexcitation. A retrograde conducting AP allows ventriculo-atrial (VA) conduction, creating a reentry circuit that mediates orthodromic atrioventricular reentry tachycardia (OAVRT). This condition is well described in humans and small animals, but has not been reported previously in horses. Objective: Describe clinical and electrocardiographic findings of horses with retrograde AP co...
