Echocardiographic and hemodynamic indices of myocardial contractility simultaneously evaluated in telemetered beagle dogs: A HESI-sponsored cross-company evaluation

Seasonal and circadian variations of hemodynamic and electrocardiographic parameters in telemetered beagle dogs

the effect of phenoxybenzamine on myocardial contractility in dogs

the cardiac action of phenoxybenzamine (dibenzyline) was studiedusing the maximum rate of pressure rise in the left ventricle as a measure of myocardial contractility. cardiac function was assessed by increasing the pressure load on the heart and measuring contractility as reflected by dp/dt. dibenzyline was found to change the cardiac response to pressure load. the rate of pressure increase in...

Reference values of M-mode echocardiographic parameters and indices in conscious Labrador Retriever dogs

Breed-wise standard echocardiographic values in dogs have been reported as there is variation in body and chest conformation which limits the application of data of one breed for other breed. Labrador Retrievers being originated from hunting dogs, might have different echocardiographic values from standard normal range of other dog breeds. So, the present study was aimed to determine the M-mode...

Echocardiographic indices in normal German shepherd dogs

Sixty clinically normal German shepherd dogs, 31 males and 29 females, ranging in age from 1 and 5 years and with a body weight ranging from 22 to 37.2 kg, were examined by the two-dimensional mode, M-mode, and Doppler echocardiography. In Doppler mode, the mitral valve flows were obtained, where the aim was to determine the velocity peaks and ratios of the E and A waves and the mitral E wave d...
