Less responsive nerve stimulation causes the rate and strength of the hearts contractions to
Added by Brandon R.
Step 1
Step 1: When nerve stimulation is less responsive, it means that the signals from the nerves to the heart are not as strong or frequent. Show more…

The parasympathetic fibers of the vagus nerve slow the heartbeat decrease the force of cardiac contractions speed up the heartbeat. increase the force of cardiac contractions
Madhur L.
The activity of the heart depends on intrinsic properties of cardiac muscle and on neural factors. Thus, (a) vagus nerve stimulation of the heart reduces heart rate, (b) sympathetic nerve stimulation of the heart decreases time available for ventricular filling, (c) sympathetic stimulation of the heart increases its force of contraction, (d) all of the above.
