Taquicardia ventricular

MEDEST - December 17, 2014 - By Ken Grauer
  • "Rule #1: Is there extreme axis deviation during WCT
    • Extreme axis deviation is easy to recognize. The QRS complex will be entirely negative in either lead I or lead aVF. The presence of extreme axis deviation during a WCT rhythm is virtually diagnostic of VT.
  • Rule #2: Is lead V6 all (or almost all) negative?
    • IF ever the QRS in lead V6 is either all negative (or almost all negative) then VT is highly likely.
  • Rule #3: Is the QRS during WCT “ugly”?
    • The “uglier” the QRS the more likely the rhythm is. VT originates from a ventricular focus outside of the conduction system. As a result VT is more likely to be wider and far less organized (therefore “uglier”) in its conduction pattern"
