    Brugada Criteria for Ventricular Tachycardia

    Distinguishes ventricular tachycardia from supraventricular tachycardia.
    When to Use
    Why Use

    Patients with wide QRS-complex tachycardias (WCT).

    • When none of the VT criteria is present, VT is still present in 15% of cases (Jastrzebski 2016).  If there is doubt, the patient should be treated for VT.
    • Using only the first two steps has been shown to yield an 81-96% positive predictive value for VT (Garner 2013).
    • Although Brugada initially reported an accuracy of 98%, four subsequent studies have found accuracies ranging from 77-85%.
    • May have limited agreement among physicians (in one study, up to 22% of emergency physicians disagreed on EKG interpretation using the criteria).
    • Because current EKG algorithms misdiagnose WCTs 10% of the time (Grimm 1996), knowledge of diagnostic algorithms like the Brugada Criteria is important.

    • The algorithm uses a stepwise approach to provide a sensitive, specific, and accurate way of differentiating SVT with aberrant conduction from VT.

    • Using a stepwise approach prevents errors from being made in the differential diagnosis of tachycardias with a wide QRS complex.

    • Compared to other criteria, this criteria is less prone to mistakes causing potentially fatal outcomes.
