Echocardiographic parameters were recorded, measured and statistically analyzed on a population of normal cats under pentobarbital anesthesia. Results of the study are similar to those obtained by previous investigators. However, this investigation demonstrates the depressant effect of pentobarbital anesthesia on cardiac contractility and the percent change in the left ventricular minor diameter. Analysis by correlation indices shows a positive relationship between the left ventricular diastolic and systolic dimensions, the left ventricular diastolic dimension and the E to F slope of the anterior mitral valve, the left ventricular systolic dimension and the E to F slope, the percent change in left ventricular minor diameter and the velocity of circumferential fibre shortening of the left ventricle and the left atrial dimension and body weight. A negative correlation exists between the left ventricular dimension at systole and the percent change in minor diameter of the left ventricle and the velocity of circumferential fibre shortening.
在戊巴比妥麻醉下，对一群正常猫记录、测量并统计分析了超声心动图参数。本研究结果与先前研究者所得结果相似。然而，本次调查证明了戊巴比妥麻醉对心脏收缩力以及左心室短径百分比变化的抑制作用。通过相关指数分析表明，左心室舒张和收缩直径之间、左心室舒张直径与二尖瓣前叶E至F斜率之间、左心室收缩直径与E至F斜率之间、左心室短径百分比变化与左心室圆周纤维缩短速度以及左心房直径与体重之间呈正相关。左心室收缩期直径与左心室短径百分比变化以及圆周纤维缩短速度之间存在负相关。
