What does it mean to have an incomplete right bundle branch block?

What does it mean to have an incomplete right bundle branch block?

Not much: It is a benign EKG finding related to a slight delay in the conduction system (like electrical wiring) of the heart. It is more common in those with an atrial septal defect (hole between left and right heart) but in general is benign, nothing to worry about. ...Read more

Bundle Branch Block (Definition)

There are 2 main branches of the heart's electrical system within the ventricles, the right bundle branch and the left bundle branch. Additionally, the left bundle branch has two sub-branches, the antero-superior fascicle and the posteroinferior fascicle. When one or more branches are disrupted, the resultant electrical abnormalities can be ...Read more

Hoping you can tell me, is right bundle branch block (rbbb) something to really stress over everyday?

Hoping you can tell me, is right bundle branch block (rbbb) something to really stress over everyday?

Would it be possible that a rbbb (right bundle branch block) cause a heart murmur?

Would it be possible that a rbbb (right bundle branch block) cause a heart murmur?

No: A rbbb is a pattern seen in the ECG where the electrical impulse is delay or interrupted as it spread along the heart. Prevalence increase with age. At 80 y/o close to 10% people can have it. Somewhat benign but an evaluation need to be done to r/o heart and lung conditions. Conditions like copd, cad, myocarditis, valvular heart disease, and other structural heart conditions. ...Read more

Right bundle branch block and Z-pack (Azithromycin) prescribed for infection. Haven't taken yet, any concern for heart issues with RBBB and Azithro?

Right bundle branch block and Z-pack (Azithromycin)  prescribed for infection. Haven't taken yet, any concern for heart issues with RBBB and Azithro?

BBB: ECG QT interval prolongation can be a concern with azithromycin,the bundle block adds to the measured QT interval ,however the more relevant measure is the JT interval that ECG machines don't record/measure,consult locally with the prescribing physician.Also don't delay antibiosis with out the prescriber being aware. ...Read more

My 17 year old cousins EKG showed leftward axis and incomplete right bundle branch block. It's abnormal for her age but what does it mean?

My 17 year old cousins EKG showed leftward axis and incomplete right bundle branch block. It's abnormal for her age but what does it mean?

Ecg: Those findings are not usual for the age but don't necessarily imply any specific pathology present. They need to put together with the rest of her clinical situation to assess whether any explanation suggests itself. ...Read more
