This study examined the blood flow velocities and flow patterns in the normal dog using pulsed wave spectral Doppler echocardiography in eight areas of the heart. Two breeds of dogs, aged between 8 and 112 weeks and of both sexes, were used. The dogs were fully conscious and no drugs were used. The areas examined were the mitral valve, left atrium, tricuspid valve, right atrium, aorta, left ventricular outflow tract, pulmonary valve and the right ventricular outflow tract. The peak and mean velocities, direction of flow and whether flow was systolic or diastolic was determined for each of these flow areas. Additionally each of these waveforms were described. Aortic flow was also measured from the thoracic inlet by continuous wave Doppler.
