The results support the view that in man cardiac responsiveness to histamine appears at a very early stage of development. It might also be suggested that in human embryonic and foetal hearts the adenylate cyclase activating, positive chronotropic and ventricular inotropic effects of histamine are mediated via H2-type histaminergic receptors.
