The brain may independently control cardiac rate, contractility, and atrioventricular conduction through specific actions of individual autonomic post- and preganglionic neurons.
The idea is introduced that cardiac rate, contractility or atrioventricular (A-V) conduction spread may be controlled independently by the brain. Limited data from reflex studies are cited to support this view. 2. Evidence is presented that individual autonomic post- and preganglionic neurons have quite specific actions on the heart. Premotor and other central neurons can have preferential actions on heart rate, contractility or A-V conduction. 3. The functional implications of selective cardiac control are discussed.
Salo et al. (Fri,) conducted a review in Cardiac function control by the brain. Differential control of cardiac functions by the brain was evaluated. The brain may independently control cardiac rate, contractility, and atrioventricular conduction through specific actions of individual autonomic post- and preganglionic neurons.
