深支又依次分出动脉圆锥支、左缘支和前室间隔支。
The deep branch (anterior descending branch) gives off arterial cone, left fringe and anterior interventricular septum branches in proper order.
前降支又依次分出动脉圆锥支、左缘支和前室间隔支。
The anterior descending branch gives off arterial cone, left fringe and anterior interventricular septum branches in proper order.
室间隔支供应室间隔的大部分、房室束和左右束支近段（图3）。
The septal branches course medially and supply the majority of the interventricular septum, as well as the atrioventricular (AV) bundle and proximal bundle branch (Fig 3) (7).
若无第二室间隔支，中、远段的分界为第一室间隔支与心尖的中点。
If this is not the case, the middle and distal LAD artery are split at a distance halfway between the first septal perforator and the apex of the heart.
冠脉间隔支选择造影后经球囊试堵、导管中心腔造影及床旁超声心动图监测确定靶间隔支。
The methods of target septal branch selection included balloon occlusion test, angiography through the catheter lumen, and ultrasonic echocardiogram monitor.
室间隔及其他部位侧支血流丰富。
Ventricular septal and other positions had abundant blood stream.
结果左前降支狭窄组存在局部血流加速、左前降支远端或前间隔分支内逆向血流。
Results The patients with stenotic left anterior descending coronary artery were found localized acceleration flow or retrograde flow by echocardiography.
目标：多时相室间隔运动和间隔-侧壁心尖左心室(LV)运动为左束支传导阻滞的心电图特征。
Objective: Multiphasic septal motion and septal to lateral apical left ventricular (LV) motion are echocardiographic characteristics of left bundle branch block.
