RESUMO
BACKGROUND: This study aimed at assessing the heart function of one neotropical primate (Alouatta guariba clamitans) kept in captivity using radiography, electrocardiogram (ECG) and Doppler echocardiography. METHODS: Ten adult healthy howler monkeys (A. g. clamitans) were evaluated under general anaesthesia. Vertebral Heart Scores (VHS) were obtained from radiographic studies. Ejection fraction, shortening fraction of left ventricle, left atrial/aortic root ratio, ascending aortic diameter, peak velocity of pulmonary, mitral, tricuspid and aortic blood flow and other values were measured by Doppler echocardiography. Heart rate, mean electrical axis of QRS complex, P, Q, R, S, T amplitude, P, PR interval, QRS, QT interval duration and ST segment unbalancing were measured by ECG. RESULTS AND CONCLUSIONS: Exam techniques were akin the ones used in humans. Doppler echocardiographic, radiographic, electrocardiographic and clinical parameters for howler monkey were described and correlated. The results have shown profiles of cardiovascular function and structure of A. g. clamitans.

No Brasil, enfermidades infectocontagiosas são as mais prevalentes na casuística de caninos domésticos, sendo a erliquiose monocítica canina, causada pela bactéria Ehrlichia canis, uma das mais graves. Entre os sintomas da doença, os mais descritos pela literatura são: letargia, anorexia, epistaxe, hemorragias, anemia e trombocitopenia. Estudos recentes, contudo, indicam que a doença também está associada a diversos sintomas relacionados a lesões cardíacas. O presente trabalho avaliou cães comprovadamente infectados pela E. canis com o emprego do eletrocardiograma antes e após o tratamento padrão com doxiciclina (10mg/kg), visando identificar alterações típicas causadas pela doença.(AU)
The contagious diseases are the most prevalent in Brazilian domestic canines, and one of the most severe is the monocytic ehrlichiosis, caused by Ehrlichia canis bacteria. Among the symptoms of the disease, the most prevalent are apathy, anorexia, epistaxis, hemorrhage, anemia, and thrombocytopenia. However, recent studies indicate association between the disease and diverse symptoms related to cardiac injuries. This article evaluated dogs undoubtedly infected by E. canis through electrocardiogram applied before and after the standard treatment with doxycycline (10mg/kg), aiming to identify typical variations caused by the disease.(AU)

This study evaluates the clinical findings obtained in routine screening examinations in cats with obstructive feline lower urinary tract disease at the time of service. Twenty-six cats with urethral obstruction were assessed by physical examination, blood pressure, electrocardiogram, and laboratory tests. Cats with signs of obstruction less than 36 hours before the service were in a state of alert, with body temperature and heart rate higher compared with cats in lethargy and stupor, obstructed up to 36 hours. The results revealed that 30.76% of the cats were hypertensive (>140mmHg). Arrhythmias were found in 15.38% of the cats with potassium >8.5mEqL. Creatinine, phosphorus, magnesium, potassium, and lactate concentrations were higher in cats obstructed more than 36 hours. All these data claim that a protocol of examinations should be established for obstructed cats, principally to stabilize the cat before the anesthesia for unobstruction.
