Objective: The treatment of syncope depends largely on its possible etiology. Therefore, identifying the cause of syncope is very important in treatment planning. Herein, we report an etiology of syncope caused by pulmonary hypertension (PH) associated with canine filariasis, followed by syncope...

Transient hypophosphatemia is often detected in humans following generalized tonic-clonic seizures (GTCS), and serum phosphorus concentration (sPi) serves as a marker to differentiate GTCS from syncope. The objective of this retrospective study was to assess the usefulness of hypophosphatemia as a...

Objective: To determine if serum cardiac troponin I (cTnI) concentration distinguishes between cardiogenic syncope and collapsing dogs presenting with either generalized epileptic seizures (both with and without cardiac disease) or vasovagal syncope. Animals: Seventy-nine prospectively recruited ...

Tracheal collapse is a condition in which the dorsoventral portion of the tracheal ring is compressed due to progressive degeneration of cartilage. Tracheal collapse is common in small breed dogs around the age of seven. The case animal is a nine years old male Pomeranian dog with a body weight of...

A 10-year-old male entire Cavalier King Charles Spaniel was referred for investigation of frequent episodes of transient loss of consciousness during periods of rest as well as severe stertor and inspiratory dyspnoea. Echocardiography revealed degenerative mitral valve disease in stage B1 ACVIM...

Pericardial defect is a rare condition, with risk of cardiac chamber strangulation or incarceration. Surgical correction is recommended when clinical signs are unmanageable and to decrease the risk of thromboemboli. A 15-year-old, 4.1-kg, spayed female Shih Tzu dog presented to the hospital with a...

Background: Atrial fibrillation (AF) is associated with increased risk of sudden cardiac death (SCD) in humans, independent of secondary risk factors such as thrombogenic disorders. In dogs, SCD is described in a number of heart diseases, but an association between AF and SCD is unreported....

This article reports on a case of syncope and mitral valve disease in an 8-year-old male Cavalier King Charles dog focusing on its diagnosis and treatment.

A 14-year-old intact male West Highland White Terrier weighing 6.9 kg was admitted to the Tokyo University of Agriculture and Technology Animal Medical Center with the complaint of syncope after showing signs of nausea during feeding. Sinus arrest induced by deglutition was confirmed using a Holter ...

Background: Syncope is a transient loss of consciousness occasionally occurring in dogs with advanced myxomatous mitral valve disease (MMVD). Objective: (1) To study ECG changes during syncopal episodes in dogs with advanced MMVD and (2) to compare the occurrence of arrhythmias and changes in heart ...
