摘要: Seventeen patients with left bundle branch block were studied using standard echocardiographic techniques employing a strip chart recorder. All 17 found to have specific findings of abnormal septal motion uniquely different from previously described forms in volume overload states the right ventricle as well coronary artery disease. The abnormality demonstrated is very dynamic posterior interventricular septum occurring within 0.04 seconds onset QRS and preceding anterior ventricular wall during ejection. This type not seen other appears be for block.
