R-WAVE PROGRESSION

Note: Evaluates rotation of axis in transverse plane.
Normal Progression S>R(V1); R>S(V6); transition/isoelectric lead is V3 - V4.
Early Transition (V1-V3) counterclockwise rotation, RVH, RAD, posterior MI, incomplete RBBB (V1).
Late Transition (V4-V6) clockwise rotation, LVH, LAD, anterior MI, breast attenuation, LBBB.
