One hundred and 10 normal subjects were studied by pulsed Doppler velocimetry to determine the range of values of blood velocity across the cardiac valves and in the great vessels. Modal peak velocities of 1.55 m/s occurred in the left heart, but right heart peak velocities were lower. In most sites a statistically significant inverse relation between peak velocities and age or body surface area was found. Time to peak velcocity in the pulmonary artery and ascending aorta increased significantly with age and was shorter in the aorta than in the pulmonary artery. These data were developed to serve as standards for the assessment of values recorded in patients with congenital and acquired cardiac disease.
对100名正常受试者进行了脉冲多普勒测速研究,以确定通过心脏瓣膜和大血管的血流速度值范围。左心的模态峰值速度为1.55米/秒,但右心的峰值速度较低。在大多数部位,发现峰值速度与年龄或体表面积之间存在统计学上的显著负相关。肺动脉和升主动脉的峰值速度时间随年龄显著增加,且主动脉中的峰值速度时间比肺动脉中的短。这些数据被制定为评估先天性和后天性心脏病患者记录值的标准。
