Sympathetic/parasympathetic nerve fibres decrease rate of heart beat.

What happens if the sympathetic nerve supply to the heart is cut off?

Assertion : Neutral signals through sympathetic nerves can increase the strength of ventricular contraction Reason : Parasympathetic neutral signals synergistically act with sympathetic neutral signal to increase the cardiac output.
