EpistemisBrugada Algorithm: Ventricular Tachycardia vs. Supraventricular Tachycardia with Wide QRS
Four sequential steps applied in order: the first one that is affirmative diagnoses ventricular tachycardia and stops the algorithm. When in doubt, any wide QRS tachycardia is treated as ventricular.
Required inputs
| Variable | Example value |
|---|---|
| Step 1 · Absence of RS complex in all precordial leads | — |
| Step 2 · Interval from the beginning of the R to the nadir of the S greater than 100 ms in some precordial | — |
| Step 3 · Atrioventricular dissociation (or capture or fusion beats) | — |
| Step 4 · Morphological criteria for ventricular tachycardia in V1-V2 and V6 | — |

This page explains the score but does not run it. In Epistemis, the calculator validates units, flags values outside physiological ranges, and provides the interpretation that a number alone cannot convey.
Epistemis is educational review material. It is not a medical device, does not diagnose or prescribe treatment, and does not replace formal medical training, current clinical guidelines, or professional clinical judgment.
