WebRBBB also has the slurred S wave in V 5/6 (and usually also lead I since it is similar to V 6). The slurred S wave needs to be either wider that the R wave or > 40 ms (1 little square). The slurred S wave has a rounded "bottom", as opposed to a pointy bottom, and it is wide. WebHowever, the first R-wave is larger than the second R-wave, which is not the case in RBBB. This suggests that the rhythm is not a supraventricular tachycardia conducted with RBBB, …

WebSVT with RBBB (supraventricular tachycardia with right bundle branch block) pattern as evidenced by the slurred S wave in lead I and aVL and rSR’ pattern in V1. The right bundle conduction is slower during tachycardia and hence right bundle aberrancy is more likely to occur than left bundle aberrancy. WebAug 28, 2006 · 2) A secondary R wave is seen in V1. The secondary wave is usually broad and slurred (the complex in V1 may be rsr’, rSr’, RSr’, RSR’ or M-shaped). Additional features frequently seen in RBBB include: 1) Deep, slurred S waves in left precordial leads (typically V4,V5,V6). 2) Deep, slurred S waves usually seen in lead I and also aVL. ready seal stain reviews longevity
