Importância da avaliação eletrocardiográfica e da pressão arterial de cães idosos atendidos no Hospital Veterinário da UFCG, Campus de Patos / PB.

Abstract

Dogs' lifespan currently has increased considerably due to the sentimental value and the proximity that these animals acquired with their tutors. Medical tests such as electrocardiograms and measuring blood pressure increasingly available at the clinic of small animals are contributing are contributing to this better quality of life. The aim of this work was to evaluate and trace an electrocardiographic profile and blood pressure of old dogs examined at the Veterinary Hospital of UFCG, campus Patos, Paraíba. 26 small dogs were used, with an age of 11,4 +1,8 years which were performed electrocardiographic, measurements of blood pressure by the oscillometric method. At the end of the study the results were treated descriptively. From animals studied, 46.1% showed values of P-wave and complex QRS duration described above average for the species and size. The T wave showed a negative 46.1% in tracings, positive in 42.3% and 11.5% biphasic, with variations greater than 25% in relation to height of the R wave in 19.2 tracings, smaller than 25% in relation to the R wave height in 76.9% of the traced and equal to 25% in relation to the R wave height 3.8% tracing. The S-T segment was normal in 53%, with 15.3% supraunleveling _ with and with ST depression in 30.7%, but the supraunleveling and ST depression found were within normal limits for the species and size. Only 26.9% of the animals showed heart rhythm called regular sinus rhythm, 73% had normal sinus arrhythmia. As blood pressure, only 9 of the studied animals (36.7%) had SBP, DBP and MBP within the standards indicated in the literature. It can be concluded that although electrocardiographic variables and blood pressure values of the study animals present themselves out of the normal pattern for the species, is likely to note that these values can be caused by age and senile animal condition.
