AV junction has a rate of 40-60.
It is a built-in rate at which it initiates electical impulses, meaning that the AV node has a rate range at which it usually produces impulses.
fewer than 40 bpm
P waves occur from the sinoatrial node and indicate the atrial component of a heart rate. Junctional rhythms occur when the AV node (below the sinoatrial node) takes over. Therefore, in most junctional rhythms there are no p waves.
40-60 beats per minute
The intrinsic rate of the AV node, also known as the inherent pacemaker rate, is the rate at which the AV node generates electrical impulses when not influenced by outside factors. It is typically around 40-60 beats per minute and serves as a backup pacemaker if the SA node fails to function properly. The AV node's intrinsic rate helps to regulate the heart rate and maintain cardiac function.
AV node is responsible for the delayin transmission of impulse generated in the SA node.This delay of impulse transmissions is called AV nodal delay. It is about 0.09 sec.Causes of AV nodal delayi. Junctional fibres of the AV node are very small in size.ii. Prolonged refractory periodof AV node.
junctional fibers leading into the AV node have very small diameters
My physician mentioned a possible fix (ablation) to attempt to correct an 'Accelerated Junctional Arrhythmia' in addition to me already having a Pacemaker to support my 'Complete AV Heart Block'. He did not go into detail, and we will re visit this discussion in the coming week. He says it may not be any easy procedure. Exactly what type of ablation is he talking about about and what could he have possibly meant by this procedure not being too easy?

An AV shunt is surgically implanted. An internal fistula is an abnormality that develops in tissues/between areas of anatomy.
