The Evaluation of Position of Interventricular Septum Measured by Transitional Zone of EKG

The position of interventricular septum, which was measured by transitional zone of EKG, was compared with that measured by 2-D echocardiography in 51 patient. 1) The position of interventricular septum measured by 2-D echocardiography was very similar to that measured by transitional zone of EKG. 2) Extensive AMI (Anterior Myocardial Infarction) and LBBB showed moderate differences between two method. 3) RBBB and replaced mitral valve state showed severe differences between two methods. Transitional zone of EKG was helpful to define the position of interventricular septum except extensive AMI, bundle branch block and replaced mitral valve state.
