Interdependence of blood pressure and heart period regulation in mild hypertension.

abstract：:To determine if a remodeling of the collagen matrix would occur in the absence of hypertrophy and cell necrosis and if such a remodeling could alter active and passive stiffness of the intact myocardium, five rats with genetic hypertension (SHR) were treated (SHRT) with hydralazine for 32 weeks, beginning at four week...
