Qs in v1 and v2
WebDominant R-wave in V1/V2. As seen in Figure 10 (left-hand side) the R-wave in V1–V2 is considerably smaller than the S-wave in V1–V2. Dominant R-wave in V1/V2 implies that the R-wave is larger than the S-wave, and this may be pathological. If the R-wave is larger than the S-wave, the R-wave should be <5 mm, otherwise the R-wave is abnormally large.
