A standardised echocardiographic protocol was applied to 18 healthy calves for the estimation of 51 anatomical and functional cardiac variables. These variables were measured in a long axis and a short axis view of the heart, and both two-dimensional and cursor-directed time-motion (M-) modes were used. The repeatability of each of the measurements was estimated by comparing values obtained twice within 24 hours, and most of the 51 variables showed a high degree of repeatability. Statistical analysis revealed a close correlation between cardiac measurements taken post mortem and by in vivo echocardiography, and between the echocardiographic values obtained in different scanning planes of the heart or ultrasonic modes, indicating that quantitative echocardiography is a reliable technique in calves.
采用标准化超声心动图检查方案对18头健康犊牛进行检查，以评估51项心脏解剖学和功能变量。这些变量在心脏的长轴和短轴视图中进行测量，同时使用二维和光标引导的时间-运动（M）模式。通过比较24小时内两次获得的值来评估每项测量的重复性，51项变量中的大多数显示出高度重复性。统计分析表明，死后心脏测量值与活体超声心动图测量值之间，以及在心脏不同扫描平面或超声模式下获得的超声心动图值之间存在密切相关性，这表明定量超声心动图在犊牛中是一种可靠的技术。
