The cardiac stimulant actions of nine β-adrenoceptor blocking agents were examined in
kitten papillary muscles and in isolated atria of kittens and guinea pigs to determine to what …

The chronotropic and inotropic effects of fourteen β-adrenoceptor blocking agents were
studied in vitro on preparations of isolated heart muscle from kittens and guinea pigs. Most …

The pattern of antagonism between isoproterenol and various β-adrenoceptor blocking
agents was explored in spontaneously beating right atria and in driven left atrial strips from …

Abstract 1 The actions of 4-(2-hydroxy-3-isopropylaminopropoxy) phenyl acetamide (ICI

A radioligand that selectively labels β 1-adrenoceptors, 3 H-(−)-bisoprolol (3 H-BIS), is
introduced. The binding properties of 3 H-BIS to membrane particles of kitten heart are …
