When blood returns to the heart, it follows a complicated pathway. If you were in the bloodstream, you would follow the steps below one by one. Oxygen-poor blood (shown in blue) flows from the ...

If an action potential is able to traverse the accessory pathway and then return retrograde through the AV node ― or vice versa ― a reentrant circuit can be created, resulting in AVRT.
