Resum

Supraventricular tachycardias encompass tachycardias that originate in structures located above the bundle of His bifurcation. In general, supraventricular tachycardias can be atrial, of the AV node, or mediated by an accessory pathway. Most of them are due to reentry mechanisms, from focal to local to macro atrial reentries. For their proper diagnosis, first, a good graphical recording using a 12-lead ECG is fundamental, although sometimes a rhythm strip or a Holter can lead to a correct diagnosis. Second, once the recording has been obtained, it should be analyzed following a series of steps that includes verifying what it is like and the rate of the atrial activity as well as the relationship between the atria and the ventricles (P/QRS). An adenosine infusion or vagal maneuvers can help establish the final diagnosis.
