title: Isometric relaxation of hypertrophied right ventricle in rats.
abstract: In rats with experimental hypertrophy of the right ventricle due to chronic increase in pressure load -dP/dTmax, a parameter of isometric relaxation, is significantly reduced at a stage of impairment of myocardial function at which the parameter of isometric contractility still remains unaffected.
