- Brugada criteria can be used to differentiate between supraventricular tachycardia (SVT) and ventricular tachycardia (VT)12. The criteria are as follows:
- QR or QS complex suggests ventricular tachycardia.
- R or RR complex without initial q-wave suggests SVT.
- VT is frequently a RBBB pattern (upright in V1) or LBBB (downward in V1).
- If yes to any of these criteria, ventricular tachycardia (VT) is likely.
- If "no" to all four of these criteria, supraventricular tachycardia (SVT) is likely.The criteria have very high sensitivity (90%) and specificity (60–90%) for diagnosing ventricular tachycardia1.
