Describe specifically what happens at the SA node and AV node in order to increase HR during exercise. Why is the dromotropic effect at the AV node necessary to increase or decrease HR? - ANSWER neural stimulation of the SA node affects the frequency of action potentials emitted from the SA node, through the internodal tracts and into the AV node. neural stimulation of the AV node affects the rate of conduction though the AV node Both need to be increased (SS) or decreased (PS) to increase...
