Pathophysiologic substrate for ventricular tachycardia in coronary artery disease and non-ischemic heart disease

Israel Journal of Medical Sciences

Abstract

Sustained uniform monomorphic ventricular tachycardia is usually due to abnormalities of conduction, including coronary artery disease and right ventricular dysplasia. These conduction abnormalities are due to non-uniform anisotropy which is characterized by fragmented electrograms. Less is known about the pathophysiologic substrate of sustained ventricular tachycardia in the absence of coronary artery disease or cardiomyopathy.

Cardiac Conduction System

The cardiac conduction system is a specialized tract of myocardial cells responsible for maintaining normal cardiac rhythm. Discover the latest research on the cardiac conduction system here.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Arrhythmogenic Right Ventricular Dysplasia

Arrhythmogenic right ventricular dysplasia is a congenital cardiomyopathy that is characterized by infiltration of adipose and fibrous tissue into the right ventricle wall and loss of myocardial cells. Primary injuries usually are at the free wall of the right ventricular and right atria resulting in ventricular and supraventricular arrhythmias.
