I have been diagnosed with a right bundle branch block of the heart. Can I reverse this?

I have been diagnosed with a right bundle branch block of the heart. Can I reverse this?

Probably not: A right bundle branch block is either slowed or blocked conduction in one of the three fascicles ("wires") that connect the top chambers to the bottom chambers of the heart. Generally speaking, if the right bundle block has been there a while, it'll stay. Sometimes they come and go, but that's like an extension cord on the fritz and sparking. Good news: you'll be fine with just the left bundle. ...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

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

What is an incomplete right bundle branch block in the heart?

What is an incomplete right bundle branch block in the heart?

Electrical slowing: The conduction of electricity in the lower chambers of the heart occurs through the left and right bundles. An incomplete right bundle branch block is an insignificant finding, representing a slight slowing in the electrical conduction as it passes through the right side of the heart. Please be aware that this has nothing to do with blockages in the arteries or heart attacks. ...Read more

What is the connection between right bundle branch block with slow heart beat?

What is the connection between right bundle branch block with slow heart beat?

It depends: Right bundle branch block (rbbb) in itself is usually a benign disturbance of conduction system of the heart. It usually does associated with adverse effects. However, it may be a part of other serious conduction disorders of heart (like high degree av block).
Therefore, it may not be the cause of but a part of findings in a slow heart rate. Also remember, slow heart rate is not always bad. ...Read more

So now my 17 year old cousin has a grade 2 heart murmur, leftward axis, and incomplete right bundle branch block. What can all this mean? I'm scared!

So now my 17 year old cousin has a grade 2 heart murmur, leftward axis, and incomplete right bundle branch block. What can all this mean? I'm scared!

My best guess: Heart murmur, left axis deviation of the frontal plane qrs axis, and an rsr' in v1 (irbb) makes pediatric cardiologists suspicious of an osmium primum atrial septal defect. Typically, this presents in the first few months or years of life, but it can present in adulthood. To sort this out, your cousin needs an echocardiogram. ...Read more

My recent EKG reads sinus brady with 1st degree AV Block incomplete right bundle branch block. Am I at a greater risk for heart failure or a fib?

My recent EKG reads sinus brady with 1st degree AV Block incomplete right bundle branch block. Am I at a greater risk for heart failure or a fib?

Correct: AllButBrady: Are c/w damaged muscle cells, most commonly from blood supply issues (artery disease, by US autopsy studies >8 decades, present 1/2 population by age 7), arteries enlarge, not narrow, thus not clinically apparent for decades until vulnerable plaques rupture releasing WBCs triggering clots & blood flow to capillaries blocked. Same issue underlying atrial fib. All issues missed by conventional tests ...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?

Not really: Rt bbb is a common ekg finding and it may occur in some medical conditions. But it is also common in some people with normal heart
it occurs in conditionsthat effect the right ventricle or the lungs. If you are otherwise healthy and no other symptoms and your doctor gave you clean chit, than you do not need to stress over it every day. ...Read more

Is heart block the same as rate related left bundle branch block?

Is heart block the same as rate related left bundle branch block?

Not the same: Both are types of fatigue in the heart's wiring system. 1st degree heart block is when there is a delay in the signal getting from atria down to ventricles. That's minor. In more advanced heart block, some beats don't get through at all. In lbbb, there is no block between atria + ventricles but there is a delay in the signal spreading within the ventricles, which doesn't cause symptoms by itself. ...Read more

I have congestive heart failure with a 30% ejection fraction, hypertrophic cardiomyopathy, and left bundle branch block is it safe for me to fly?

I have congestive heart failure with a 30% ejection fraction, hypertrophic cardiomyopathy, and left bundle branch block is it safe for me to fly?

Depends: It depends on your overall health. Do you have an icd, are you on daily oxygen, daily medications, can you sit for exended lengths of time, how long is the flight? Commercial airlines have cabin pressures set to about 7000ft. So if you can tolerate that altitude (denver is about 5600ft), air travel may be ok. Discuss with your doctor. Tsa will need to know if you have an icd. ...Read more

Do you know of any heart conditions that have been misdiagnosed as chronic fatigue syndrome? Had an ECG which showed bundle branch block. I have cfs.

BBB: In this day and age it would be very unlikely to have a heart condition misdiagnosed as chronic fatigue although it has probably happened in the past...... Even the least astute doc has access to diagnostic tools and consultants. Bundle branch blocks (especially right sided) are common and are not directly associated with fatigue. ...Read more

What is a sinus rhythm with a right bundle branch block?

What is a sinus rhythm with a right bundle branch block?

Wiring of heart: Sinus rhythm means that the electrical activity that controls the contraction of the heart, starts in the sinus node. Right bundle branch block means that the right bundle (part of the electrical wiring) does not conduct the impulse which changes the appearance of the ekg. Right bundle branch block as opposed to left bundle branch block is usually benign. ...Read more

Is it okay to smoke weed with a right bundle branch block?

Is it okay to smoke weed with a right bundle branch block?

No: Among the bad things smoking marijuana does to the heart and lungs are the noticeable rise in heart rate and blood pressure, the increased demand for oxygen by the contracting heart muscle, followed by vasodilation (blood vessels relax and dilate) with a drop in blood pressure as smoking mj continues; the abnormal rhythms in the upper heart, and maybe abnormal ventricular (lower heart) rhythms. ...Read more

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

Is it safe for someone with a right bundle branch block to take the medications Elavil/Desryl seperate and/or together?

RBBB: Both these medications list cardiac conduction abnormalities, and RBBB is one, as contraindications to their use. I have seen patients with chronic, longstanding RBBB tolerate low dose Elavil in past years. Other antidepressants may be considered in such patients. Your pharmacist or a cardiologist would be better qualified to answer this question, however. ...Read more

Can I run if I have a right bundle branch block? Dr found it on an ekg and she didn't seem too worried about it. I didn't know if the slow rate is ok.

Check to see; IRBBB: If you say your doctor isn't worried about it then, can you ASK if she means you've an INCOMPLETE RBBB as opposed to a RBBB that's NOT incomplete. The former is believed likely benign in the vast majority of people & is found in many asymptomatic healthy individuals. The latter needs a bit more work to say that it's benign.
