WebMay 10, 2024 · In RBBB, there should be some ST depression in V1-V3, discordant to (in the opposite direction of) the R'-wave. But unless there is a huge R'-wave (as in RVH), this ST depression should not exceed 1 mm. And the inverted T-wave should be proportional. WebIncomplete right bundle branch block (IRBBB) is an conduction abnormality in the right bundle branch block. While a complete RBBB has a QRS duration of 120 ms or more, an incomplete block has a wave duration between 110 and 120 ms.
