FEATURES OF RHYTHM AND CONDUCTIVITY DISORDERS IN PRIMARY CARDIAC TUMORS IN DOGS: ANALYSIS OF CLINICAL CASES, MODERN METHODS OF DIAGNOSTICS AND TREATMENT

Abstract

In recent years, the number of cases of heart tumors in dogs has increased dramatically. This trend may indicate an increase in the dog population worldwide, as well as the increasing use of various imaging methods for diagnosis, such as echocardiography, computed tomography, and magnetic resonance imaging. According to our studies, most cases of detection of cardiac neoplasms are accidental, especially when routine echocardiography with Dopplerography is performed, in such cases the animals are asymptomatic. Other animals arrive at the veterinary center mainly with acute signs of heart failure, loss of consciousness, a sharp decrease in activity, pronounced sudden shortness of breath at rest or cough, and blueness and pallor of visible mucous membranes are also observed. All these clinical signs in dogs may be due to the development of cardiac tamponade (hemorrhage) or the appearance of life-threatening arrhythmias, which requires immediate emergency measures, such as emergency pericardiocentesis and the administration of antiarrhythmic drugs. The diagnostic approach to such patients includes a clinical examination by a veterinary medicine specialist, the use of additional instrumental and laboratory methods of research.
