Re-entry Circuit Location
Re-entry circuits are found:
- Entirely within the AV node AV-nodal re-entry tachycardias (AVNRT) (Fig 1)
- In the presence of an accessory pathway in junctional tissue- AV re-entry tachycardias (AVRT), E.g., Wolff-Parkinson-White Syndrome (Fig 2)

We will look at each of these in turn.
