The relationship between interventricular septal (IVS) wall motion assessed by the echocardiogram and surface electrocardiogram was investigated in 11 patients (pts) with proximal left anterior descending coronary artery disease (LADd) during ergometer exercise. A specially devises transducer was used to obtain the echocardiograms. During exercise, 6 pts had transient ST segment depression (Group 1), whereas 5 pts had transient ST segment elevation (Group 2). During exercise-induced ischemia, the ST segment depression occurred prior to abnormal wall motion in Group 1, and lasted longer than the latter. On the other hand, the ST segment elevation was preceded by abnormal wall motion in Group 2, and returned to the control earlier than the latter. In conclusion, exercise echocardiography is useful to assess the relationship between interventricular wall dynamics and electrocardiographic changes during ischemia.
在11例患有左前降支近端冠状动脉疾病（LADd）的患者进行测力计运动期间，研究了通过超声心动图评估的室间隔（IVS）壁运动与体表心电图之间的关系。使用专门设计的换能器获取超声心动图。运动期间，6例患者出现短暂性ST段压低（第1组），而5例患者出现短暂性ST段抬高（第2组）。在运动诱发的缺血期间，第1组中ST段压低先于异常壁运动出现，且持续时间比后者更长。另一方面，第2组中ST段抬高先于异常壁运动出现，且比后者更早恢复到对照水平。总之，运动超声心动图有助于评估缺血期间心室壁动力学与心电图变化之间的关系。
