“…Quando há aumento do átrio esquerdo a onda P sofre um alargamento, resultante do prolongamento do tempo de despolarização atrial, necessitando de maior tempo para se distribuir pela câmara atrial, sendo denominada "P" mitrale (Pellegrino, et al, 2010). Essa alteração pode ser esperada em cães com endocardiose de valva mitral, cardiopatia mais comum na rotina cardiológica de cães (Perin, et al, 2007;Castro, et al, 2009).…”

O presente trabalho tem por objetivo avaliar, por meio de estudo retrospectivo, os parâmetros eletrocardiográficos e principais alterações do ritmo em cães e gatos idosos atendidos por um serviço de cardiologia veterinária. Com o aumento da longevidade dos cães e gatos domésticos, maiores cuidados com a saúde dessas espécies se fazem necessários, especialmente nos animais idosos. O diagnóstico precoce para as diferentes afecções e distúrbios do ritmo é de extrema importância para o tratamento das doenças do sistema cardiovascular. Dessa forma, é essencial entender aspectos relacionados às modalidades de exames complementares associados ao exame clínico cardiológico. O eletrocardiograma é um exame de baixo custo e não-invasivo, capaz de diagnosticar uma série de doenças cardíacas e até mesmo indícios de outros distúrbios sistêmicos. Foram avaliados os prontuários médicos e registro eletrocardiográfico de 150 animais, incluindo cães e gatos, observando-se o fato da idade senil como critério de inclusão. Arritmia sinusal, ritmo sinusal e bradicardia sinusal foram os ritmos mais prevalentes. A frequência cardíaca média foi outro parâmetro avaliado e mostrou-se em decréscimo conforme o avançar da idade. Com o presente estudo, nota-se a importância do exame eletrocardiográfico em cães e gatos idosos e a necessidade de mais estudos com populações maiores que objetivem determinar parâmetros de normalidade para animais de cada espécie nessa faixa etária.

“…The values obtained on the electrocardiogram did not differ statistically between the groups, as can be seen in Table 8. There were no changes for P wave duration and amplitude, PR and QT intervals; both groups maintained low values of amplitude of waves R and S. In addition, they showed a slight increase in the wave duration of the QRS wave duration in small breed dogs belonging to the Control Group (TILLEY, 1992;WOLF;SOUZA, 2000;CONCEIÇÃO et al, 2005;PELLEGRINO et al, 2010;SANTILLI et al, 2018).…”

The aim of this study was to identify the clinical, epidemiologic and laboratorial aspects of dogs with obesity and its possible correlation with other diseases. A total of 30 dogs were studied. Of these, 15 were obese and 15 were not. On the Control Group, there was a total of 10 females (5 neutered and 5 whole) and 5 males (all 5 neutered). On the Obese Group, 11 females (7 neutered and 4 whole) and 4 males (all 4 neutered). The tutors received a form with 12 questions about food management and physical activity, as well as pharmacological and family history. In addition, venous blood samples were collected in animals from both the Control Group and the Obese Group for a Complete Blood Count and dosage of biochemical levels (Alanine Aminotransferase, Alkaline Phosphatase, Albumin, Total Proteins, Urea, Creatinine). Measurements from the abdominal perimeter were taken and using the data the body fat percentage was calculated; an Electrocardiographic evaluation (ECG) was also made, along with the measurement of the systolic, diastolic and medium blood pressure (SBP, DBP and MAP, respectively) and heart rate (HR). The numeric data was submitted under the Analysis of Variance (ANOVA), followed by the Tukey’s Test (p<0,05), while the data regarding risk factors was analyzed on a descriptive manner. In both groups, mixed-breed dogs had a significant predominance, about 9 (60%) on the CG and 7 (46,66%) in the Obese Group. Concerning food management, 12 (80%) of the subjects of the Control Group were fed at will and 3 (20%) once a day; the numbers on the use of only pet food, pet food coupled with homemade food, and only homemade food were, respectively, 10 (66,6%), 4 (26,6%) and 1 (6,8%). Also, 11 (73,3%) had frequent physical activities, while the other 4 (26,7%) only occasionally. Additionally, 12 (80%) stayed at the backyard, while 3 (20%) lived in an apartment. There was not any relevant data relating to pharmacological and family history and, according to tutors’ opinions, their dogs were within the ideal weight. On the Obese Group, 8 (53,5%) were fed at will, 5 (33,3%) were fed on a strict and controlled manner, and 2 (13,3%) one time a day, while 9 (60%) of them were given both pet food and homemade food, 5 (33,3%) received only pet food and 1 (6,7%) received pet food sachets and fruit. In this group, 9 (60%) were out, 15 did not practice any type of physical activity, while 3 (20%) practiced frequently and the other 3 (20%) walked occasionally. There were 5 patients (33,3%) with a history of corticosteroid use, and 7 (46,7%) had a family history of obesity. Regarding tutors’ opinions on their pet’s weight, on whether they thought their pet was too thin, on ideal weight, overweight or obese, the data showed, respectively, 2 (13,3%), 4 (26,7%), 8 (53,3%) and 1 (6,7%). The percentage of fat on the Control Group for males and females was, respectively, 18,7 ± 2,2; 22 ± 3, while the abdominal circumference was of 63 ± 20 cm. On subjects from the Obese Group, the values were 40,4 ± 5; 45 ± 4,7 and 65 ± 16,8 cm, respectively. On laboratory exams, the Complete Blood Control did not show any inconsistencies with the normal range and the ALB and FAL were elevated on the Obese Group. The ECG did not show any notable changes. Both groups showed a slight increase in PAS (Control Group = 141 ± 27,72 mmHg; Obese Group = 142 ± 17,23 mmHg), and on the obese animals a raise in PAD (84 ± 22 mmHg) was also recorded. Obesity is a chronical disease that brings a series of bad consequences to the animal well-being, especially the appearance of systemic diseases; the main risk factor for its appearance is incorrect food management and low or nonphysical activity. The main way to prevent the disease is by the correct management of both factors.

Although heart rate (HR) is one of the most important clinical parameters determined via physical examinations, little information is available on the normal HR in dogs, which may be related to the high variability of body weight (BW) in this species. HR is determined by the discharge rate of the sinus node, which is dependent on the autonomic nervous system and the release of catecholamines. The allometric relationship between BW and HR in different species has been described as inversely proportional; however, this relationship has been refuted. Certain authors have reported that the relationship between HR and BW in dogs is based on temperament as well as sympathetic autonomic stimulation of the sinus node in small breeds compared with large breeds. The aim of this study was to analyze the effects of weight, sex, age and temperament on the HR, heart rate variability and serum catecholamine (epinephrine and norepinephrine) levels in dogs. We evaluated 48 adult dogs of both sexes and various breeds and ages and divided the dogs into 5 BW groups: <5kg (n = 8), 5-10kg (n = 10), 10-25kg (n = 10), 25-45kg (n = 10), and >45kg (n = 10). The measured parameters were HR, breath rate (BR) and body temperature. We also performed an ambulatory electrocardiogram and electrocardiography (ECG) test for 24 hours (Holter monitor) and determined the serum levels of the catecholamines epinephrine and norepinephrine. We observed correlations between HR and sex; differences among the weight groups with respect to ECG variables and epinephrine levels; and differences among the temperament categories for certain clinical parameters, such as HR and BR. Age affected the R wave amplitude, and an allometric relationship was not observed between HR and BW in the dogs. Our results indicated that weight was associated with variations in the ECG variables; age and sex were associated with variations in HR; and temperament had a significant influence on the HR and BR of the dogs.
