Diagnosis of arrhythmogenic right ventricular dysplasia in dogs leading to precapillary pulmonary hypertension

Relevance. The paper presents a scientifically based approach to the diagnosis of arrhythmogenic dysplasia of the right ventricle in dogs of the Boxer, English Bulldog and mestizos breeds of these breeds. The relevance of the study is determined by the increased frequency of the disease, which is later (with untimely diagnosis) the cause of the development of pulmonary hypertension. Methods and materials. A comprehensive methodological approach was used, including a superficial clinical examination, examination of the area of the pathological process using visual diagnostics and electrocardiography. The studies were conducted on clinical material from 25 sick dogs aged 5–7 years of the Boxer, English Bulldog and Mestizo breeds with symptoms of shortness of breath, lethargy and loss of consciousness. A comprehensive diagnostic approach was used, including echocardiographic examination and electrocardiography. Results. Based on the data obtained, depending on the severity of the animal’s condition, the most accurate research methods and prognostic factors for the occurrence of pulmonary hypertension syndrome and survival were determined. The main factors of congestive heart failure and the risk of sudden death have been identified.
