The Primary Alteration of Ventricular Myocardium Conduction: The Significant Determinant of Left Bundle Branch Block Pattern

<div>Results of the computer simulation: Typical LBBB patterns observed after slowing the conduction velocity in left ventricular myocardium without blocking the onset of left ventricular activation, i.e. without simulating the block in the left bundle branch. 12-lead ECG (a), vectorcardiogram (b), (H) horizontal plane, LS: left sagittal plane, (F) frontal plane.
