A right bundle branch block (RBBB) is a heart block in the right bundle branch of the electrical conduction system. [1] During a right bundle branch block, the right ventricle is not directly activated by impulses traveling through the right bundle branch. However, the left bundle branch still normally activates the left ventricle.
Intraventricular conduction delay seen in precordial/chest leads with QRS duration 100 ms. An EKG of a 25-year-old male. Intraventricular conduction delays (IVCD) are conduction disorders seen in intraventricular propagation of supraventricular impulses resulting in changes in the QRS complex duration or morphology, or both.
A right bundle branch block typically causes prolongation of the last part of the QRS complex and may shift the heart's electrical axis slightly to the right. The ECG will show a terminal R wave in lead V1 and a slurred S wave in lead I. Left bundle branch block widens the entire QRS, and in most cases shifts the heart's electrical axis to the ...
Normal 12-lead ECG A 12-lead ECG of a 26-year-old male with an incomplete right bundle branch block (RBBB). The overall goal of performing an ECG is to obtain information about the electrical functioning of the heart.
The Food and Drug Administration's new rules on "healthy" food labels are voluntary and are scheduled to take effect at the end of February.
U.S. President-elect Donald Trump criticized Ukraine's use of U.S.-supplied missiles for attacks deep into Russian territory in a Time magazine interview published on Thursday, comments that ...
Make no mistake, the howls of protest and political lobbying are coming. Alabama only got in because it is a big brand, some will say. Alabama only got in for television ratings, others will suggest.
Lev's disease continues to be an active area of research. Currently, there is limited case reports, studies, and trials revolving around the treatment for Lev's Disease. There is no case study that gives a definitive treatment option. However, its treatment and management can be approached similarly to those for atrioventricular (AV) blocks.
