다음 중 하나 이상이면 VT (AUC 0.91)

1. aVR에서 Monomorphic R (no man's area)

2. I, II, III에서 negative QRS (no man's area)

3. Opposing QRS complex in the limb leads

•

monophasic QRS complexes (QS/R) in all 3 inferior leads sharing the same polarity ( all positive or all negative, but including a notched R or QS complex), and

•

monophasic QRS complexes (R/QS) in 2 or 3 of the remaining limb leads, with a polarity opposite to that of the inferior leads

monophasic QRS complexes in all 3 inferior leads sharing the same polarity (C1–C4, all positive; C5, all negative)

monophasic QRS complexes in 2 or 3 of the remaining limb leads with a polarity opposite to that in the inferior leads (all cases).
