Abstract

The cardiomyopathies have been defined as idiopathic heart muscle disorders which are characterized by hypertrophy, dilatation, or restriction [116G]. This descriptive classification reflects our ignorance of the genesis, pathophysiology, and metabolic behavior of these myocardial disorders. Electrical stability depends upon the structural and metabolic integrity of myocardial cells. As these may be impaired in patients with cardiomyopathy it is not surprising that arrhythmias are common. In this chapter, we discuss the clinical significance and treatment of arrhythmias in primary cardiomyopathies and, when possible, comment on etiology. We will focus on hypertrophic and dilated cardiomyopathy because arrhythmias play an important role in the natural history of these conditions. The information available on the importance of arrhythmias in patients with restrictive cardiomyopathy is limited and will not be considered.
