Echocardiographic Analysis of Ischemic Interventricular Septal Dynamic : Relationship between interventricular Septal motion and Electrocardiographic Changes during Recovert from Dynamic Exercise induced-Ischemia-

The relationship between interventricular septal (IVS) wall motion and surface ECG were studied by echocardiography in 17 patients (pts) with effort angina (left anterior descending coronary antery disease (LADd)) during submaximum ergometer exercise using a specially deviced echocardiographic transducer. Of the 17 pts, during exercise, 5 pts with proximal LADd had transient ST segment elevation (Group 1) and 7 pts with proximal LADd had ST segment depression (Group 2) and 5pts with distal LADd had transient ST segment depression (Group 3). During exercise, in Group 1, percent systolic IVS thicking…
