What is the cardiac effect of a drug that blocks parasympathetic activity?
Increased firing of the sinoatrial node (SA) and conduction through the atrioventricular node (AV) of the heart, because the actions of the vagus nerve are opposed/blocked.
What is the sympathetic effect on the heart?
Heart rate increases with sympathetic nervous system. There is increase in stroke volume and cardiac output. With stimulation of vagus nerve or parasympathetic nervous system, You have decrease in heart rate. There is decrease the stroke volume and cardiac output.

What effect would a drug that blocks the parasympathetic nervous system have on peristalsis in the GIT?

What is the effect of pilocarpine on heart rate?
Pilocarpine stimulates the release of acetylcholine from parasympathetic neurons. Therefore, it stimulates the effect of vagal stimulation on the heart.

It cause cardiac arest
Does climate change earthquakes?
No. There is no primary cause-effect relationship between plate tectonics and weather patterns.
What is the effect rest has on Cardiac output?
Rest has a positive effect on cardiac output. This will promote a healthy heart rate in an individual without subjecting the heart to too much pressure.
In what way do the parasympathetic and the sympatheticnervous systems work together?
Yes. The vagus nerve is a parasympathetic nerve that is almost always stimulating the healthy heart to have a heart rate less than the inherent rate of the SA node. The sympathetic innervation on the heart is minimal and only important during exercise.
