To identify fascicular blocks you need to be able to identify a right or left axis deviation in the frontal plane. One way to do that is to use a cheat sheet like this one. WebApr 2, 2024 · Hemiblock. When either of the two halves (“hemi-”) of the left bundle is not conducting properly, a hemiblock is the result. In contrast to bundle branch blocks, the QRS duration with hemiblocks is normal, i.e., less than 0.12 s. The primary indication of a hemiblock is an abnormal axis deviation of the QRS complex.
