The greater the diameter of the fiber that much greater the heartrate will be. Because at the synaptic junction wider surface area will release more neurotransmitter materials which in turn will provoke greater action potential and thus increased heartrate.

What is the difference between a sinoatrial node and an atrioventricular node?
the SA node is located in the right atrium (one of the 4 chambers of the heart). It is where the elctro chemical conduction begins and sets the hearts pace. The AV node is located "downstream" in the conduction system of the heart and is a node where the nervous system has input into how quickly the conduction travels.....i.e. fast heart rate (tachycardia) or slow heart rate (bradycardia)
