The heart is capable of rapid changes in cardiac output: these are caused in large part by changes in the activity of the autonomic nervous system that alter heart rate, force and time course of contraction. While studies of autonomic control have focussed on heart rate and contractile mechanisms, fewer studies have considered the influence of electrical propagation across the chamber. Conduction velocity (CV) of the action potential (AP) is an important variable, which ensures efficient… CONTINUE READING
