All of the above options can cause junctional escape beats or junctional escape rhythm. SA node disease can cause the SA node to fail to depolarize, allowing the AV node or another part of the atria to take over control of the heart rhythm, resulting in junctional escape.

Hypoxia can also cause the SA node to function inadequately, prompting a junctional escape rhythm.
