Influência do desequilíbrio eletrolítico na eletrocardiografia de cães acometidos por parvovirose.

Abstract

This study aimed to demonstrate the influence of electrolyte imbalance in electrocardiographic analysis of dogs suffering from parvovirus infection diagnosed by clinical examination and confirmed by immunochromatographic test. Were classified in this study 12 dogs examined at the Veterinary Hospital of the Federal University of Campina Grande and Veterinary Medical Center Dr. Leonardo Torres both the city of Patos- PB, during the period of March-May 2013, and it was observed that they presented signs of hemorrhagic gastroenteritis by Parvovirus . The animals went through clinical evaluation and measurement of heart rate , breathing and body temperature at the time of this evaluation; blood was collected for complete blood count at the time of admission , as well as the dosage of electrolytes (Ca, Na, K, P, Mg e Cl) , in two moments: M0 ( time of admission ) and M2 (48 hours after admission ), in order to observe a possible electrolyte imbalance and variations of these rates during these different times. Fecal examination was also performed, in order to detect the presence of any endoparasitose in these animals. During the four days of admission, in each 24 hours ( M0 , M1 , M2 , M3 ) blood pressure was measured and it was performed the ECG examination in these animals . Values of Ca, Na and Mg below the reference values and in terms of the electrocardiogram were observed in these animals, and the electrocardiogram analyses showed an increase in the amplitude of the T wave as well as an elevation of the ST segment . Both segments suggest the presence of electrolyte disturbance . Based on these results, it was conclude that parvovirus gastroenteritis had influence on rates of electrolytes, a fact that reflected directly in a cardiac abnormality suggestive of hypoxia or myocardial repolarization disorder, observed by the electrocardiogram analyses, thus emphasizing the importance of performing these tests for the purpose of performing support treatment, thereby preventing future cardiac problems in these animals.
