Two types of VT (panel A and B) in the same patient (panel C during sinus rhythm). Two types of VT (panel A and B) in the same patient (panel C during sinus rhythm). Atrioventricular dissociation is present during both VTs. Note the effect of the frontal plane axis on the R:S ratio in lead V6 in RBBB shaped VT. R:S < 1 is present in case of a superior axis (panel B), but R:S > 1 with an inferior axis (panel A).
