New arguments for positive inotropic vagal influence on cardiac contractility in cats.
Vagal influences on the heart were studied in narcotized cats, in which the cardiotropic effects of sympathetic nerves, heart rate, and pre- and afterload were excluded. Under these conditions vagus nerve exerted only a positive inotropic effect probably mediated by an unknown humoral factor.
