Ultrasonic Doppler echotachocardiogram of the mitral and tricuspid valves together with polycardiogram were recorded in 44 patients with interatrial septal defect and in 18 patients with interventricular septal defect. The patients with interatrial septal defect manifested an increase of the velocity of the movement of the mitral valve during its opening, deceleration of the movement velocity in the atrial systole, a tendency towards movement deceleration during the closure, and a rise of the time of the mitral valve during its closure and opening. In interventricular septal defect, there was a tendency towards deceleration of the movement velocity of the mitral valve in the atrial systole. The velocity and time parameters of the movement of the tricuspid valve remained unchanged in patients with congenital defects under study.
对44例房间隔缺损患者和18例室间隔缺损患者记录了二尖瓣和三尖瓣的超声多普勒心动图以及心电图。房间隔缺损患者表现为二尖瓣开放时运动速度增加、心房收缩期运动速度减慢、关闭时运动有减慢趋势以及二尖瓣关闭和开放时间延长。在室间隔缺损中，心房收缩期二尖瓣运动速度有减慢趋势。在所研究的先天性缺损患者中，三尖瓣运动的速度和时间参数保持不变。
