Intraventricular block explained

Specialty:cardiology
Diagnosis:electrocardiogram

An intraventricular block is a heart conduction disorder — heart block of the ventricles of the heart.[1] An example is a right bundle branch block, right fascicular block, bifascicular block, trifascicular block.[2] [3]

Types

Types of intraventricular blocks are[4]

Intraventricular conduction delay

Intraventricular conduction delays (IVCD) are conduction disorders seen in intraventricular propagation of supraventricular impulses resulting in changes in the QRS complex duration or morphology, or both. IVCD can be caused by abnormalities in the structures of bundle of His, Purkinje fibers or ventricular myocardium.[5] [6] Nonspecific intraventricular conduction delay (NICD) is a delay with widened QRS complex but without a specific intraventricular block present.[7]
