-== Brugada Criteria ==
-*Only for regular rhythms
-*Only for treatment decision if pt is stable
-*Assume V-tach until proven otherwise
-#Absence of an RS complex in all precordial leads?
-##If yes then VT
-##If no then continue
-#R to S interval >100ms in one precordial lead?
-##If yes then VT
-##If no then continue
-#AV dissociation
-##If yes then VT
-##If no then continue
-#Morphology criteria for VT present both in V1-2 and V6?
-##If yes then VT
-##If no then possibly SVT
