title: Review of His-Purkinje System Abnormality with Case Studies.
abstract: A single beat arising as extra systole within the His-Purkinje system or from ventricle or even atrium based on conduction timing can invoke delayed conduction or block within intra-Hisian or infra-Hisian sites. This may be either manifested in the form of premature atrial or ventricular complexes or concealed as with His extra systoles. It appears commonly there is disease within the His-Purkinje system.
