Evaluating patients with ventricular arrhythmia. Role of the signal-averaged electrocardiogram, exercise test, ambulatory electrocardiogram, and electrophysiologic studies.

abstract：:The myocardium consists of three compartments: cardiac muscle cells; a nutritive microcirculation; and an extracellular matrix composed largely of fibrillar collagen. The hypertrophic remodeling of the myocardium, which involves each of these compartments, can be adaptive or pathologic. This article reviews the remode...
