Abstract
Data obtained in open-chest dog preparations indicate the involvement of myocardial catecholamines with increased inotropism after temporary ventricular ischaemia. Reserpinization and treatment with β-adrenergic blocking agents significantly reduced the rebound contractile force recorded after release of coronary artery constricting ligatures. Simultaneously recorded rebounds in coronary arterial blood flow were not correspondingly affected.Keywords
