The temporal and spatial pattern of left ventricular (LV) contraction and relaxation in 34 patients with isolated lesions of the left anterior descending artery (LAD) were studied from the LV cineangiogram in the right anterior oblique position using a computer interactive technique. The LV outline was divided into 100 equiangular radii from the center of the enddiastolic silhouette and the trajectory of contraction and relaxation of each radius measured and displayed. Patients were divided into different subsets. Classical anterior wall infarction caused impaired contraction of the distal two thirds of the anterior wall, the apex and the distal quarter of the inferior wall, with marked delay in contraction and relaxation of the border zones and hyperkinesis of the inferior wall. Spatial and temporal disturbances (akinesis and asynchrony) were marked in the other subsets. Left bundle branch block caused profound temporal delay particularly during relaxation.
采用计算机交互技术，从右前斜位的左心室电影血管造影中，研究了34例左前降支（LAD）孤立病变患者左心室（LV）收缩和舒张的时空模式。将左心室轮廓从舒张末期轮廓中心划分为100个等角半径，并测量和显示每个半径的收缩和舒张轨迹。患者被分为不同亚组。典型的前壁梗死导致前壁远端三分之二、心尖和下壁远端四分之一的收缩受损，边界区收缩和舒张明显延迟，下壁运动亢进。在其他亚组中，时空紊乱（运动不能和不同步）明显。左束支传导阻滞导致明显的时间延迟，尤其是在舒张期。
