DIY to Stop the Blood

  • 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…
