Aortic blood flow patterns: a transcutaneous Doppler study.
In 35 normal children some variables of the aortic arch blood flow were studied by transcutaneous ultrasonic Doppler technique. Mean values for peak velocity (V), acceleration in early systole (Acc), duration of the acceleration phase, as well as the area under the early phase of flow systolic complex (S) were calculated. A significant difference in S value was found between girls and boys. Some significant correlation and regression coefficients were found between the mentioned indices of the aortic blood flow on the one hand, and the weight, height, age and heart rate on the other. The highest values for the correlation coefficients occurred in girls between V and Acc on the one hand, and the weight of the subjects on the other.
