CASTRO, M.G et al. Echocardiography of clinically normal Yorkshire Terrier dogs. Arq. Bras. Med. Vet. Zootec. [online]. 2011, vol.63, n.5, pp. 1079-1086. ISSN 0102-0935. http://dx.doi.org/10.1590/S0102-09352011000500006.
The aim of this study was to establish the normal echocardiographic parameters in M-mode for Yorkshire Terrier dogs. Thirty clinically normal dogs with mean weight of 2.42±0.64kg and ages varying from one to six years old were studied. The left atrial diameter, the aortic diameter, the left ventricular internal dimension at end - diastole and end - systole, end - diastolic and end - systolic interventricular septal thickness, and end - diastolic and end - systolic left ventricular posterior wall thickness had correlation with body weight. The other M - mode variables showed no linear correlations with body weight, sex or age. The echocardiographic values found in this study can be used as reference for this breed.
