Abstract

Thirty-five clinically healthy dogs aged from 4 months to 2 years were investigated under anesthesia to estimate cardiac function, on the basis of the patterns of ultrasonic pulsed Doppler waveforms as well as various other measurements. The Doppler waveforms were similar to those of human subjects. The mean value and coefficient of variation in each measurement suggested that changes in peak rates, A/E of waveforms of left ventricular inflow tract flow, ET of waveforms of rihgt and left ventricular outflow tract flow, TVI associated with determination of the flow volume, and AT/ET of waveforms of right ventricular outflow tract flow, were clinically useful in evaluating cardiac functions.
