Functional heterogeneity of the atrial myocardium of patients with congenital and acquired heart defects

Abstract

In experiments on atrium trabeculae the heterogeneity of myocardium contractile activity in patients operated on for inborn or acquired heart defects was studied. Contractile activity was assessed in isometric regime of muscle drugs work. The degree of functional heterogeneity was reported to differ in myocardium biopsies from patients with inborn or acquired heart defects. The difference was expressed in susceptibility to stimulating action or electrical impulses and in the degree of the change of myocardium contractile activity. The study of human myocardium functional heterogeneity is likely to present a new approach to increase efficacy of the work of pathologically changed heart muscle.
