Hey everyone,

We’re back at it again with a new episode! With the help of special guest Kyle Sears, Kevin and I tackle our most requested topic yet, Wide Complex Tachycardia! Below for your reference are the Brugada and Vereckei criteria that we reference during the episode. Happy listening!

Brugada Criteria

* Is there absence of an R2 complex in all precordial leads (Precordial Concordance)?

* If yes it’s VT

* If no, is the R to S interval >100ms in one precordial lead?

* If yes it’s VT

* If no, is there AV dissociation?

* If yes it’s VT

* Morphology criteria for VT in precordial leads V1-V2 and V6

* RBBB pattern (upright in V1) or…

* LBBB pattern (downward in V1)

* If yes to above it’s VT

* If no to all of the above, likely SVT w/ aberrancy

Vereckei Algorithm

This algorithm looks at lead aVR

* Presence of initial R wave?

* If yes, it’s VT

* Presence of initial R or Q wave >40ms

* If yes it’s VT

* Notch on the descending limb of a negative onset and predominantly negative QRS?

* If yes it’s VT

* Initial to terminal ventricular activation velocity ratio <1

* Basically, VT causes slow ventricular activation then SVT w/ aberrancy, resulting in a more significantly wide QRS

* If this is present it’s VT

* If none of the above are present, likely SVT w/ aberrancy
