Additionally, the left bundle branch has two sub-branches, the antero-superior fascicle and the posteroinferior fascicle.

Is a right bundle branch block serious? I have a history of SVT, thanks!

Is a right bundle branch block serious?  I have a history of SVT, thanks!

No: Generally RBBB is not serious - it can even be present from birth. With your hx of SVT, there are certain abnormalities that need to be considered and excluded: atrial septal defect and mitral stenosis. Lung conditions can cause it. Sometime high blood pressure is the cause. There are rare causes too, but in most cases, it's an isolated finding of no significance. In itself RBBB causes no symptoms ...Read more

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

I am diabetic, age 36. I have lightheadedness problem also. Yesterday I got 'Right Bundle Branch Block' in my ECG report. Is it a serious problem?

I am diabetic, age 36. I have lightheadedness problem also. Yesterday I got 'Right Bundle Branch Block' in my ECG report. Is it a serious problem?

Not really: RBBB typically is not a worrisome finding as it does not correlate with ischemia/CAD as new LBBB does. Having said that, because you are "lightheaded", a holter monitor and resting echo may be warranted to evaluate for any other arrhythmias and for structural heart disease, respectively, if any. Last as u r of South Asian descent, pls be sure to check ur fasting lipids, glucose and don't smoke. ...Read more
