LBBB: Intermittent LAD
Report:
Sinus rhythm
SVEBs
Left bundle branch block
QRS 0.125â
Intermittent left axis deviation â50o
Comment:
Approximately 50% of LBBBs have LAD; this one had LAD 50% of the time! How or why the predivisional LBBB becomes divisional, and back again, is beyond me; but it happens. It happens even with LBBB and RAD26.
