[The diagnosis of myocardial infarction in the presence of disorders of ventricular activation for right endoventricular pacing and left bundle branch block (author's transl)].

The Authors have studied the vectocardiogram in left bundle branch block, right endoventricular pacing, myocardial infarction and right endoventricular pacing, myocardial infarction and left bundle branch block. Vectocardiographic loop analysis allows the diagnosis of myocardial infarction both in the presence of endoventricular pacing and in the presence of left bundle branch block.
