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