Can certain medications cause bundle branch block?

Can certain medications cause bundle branch block?

BBB: Certaiin common blood pressure medications and/or antiarrhythmics in very high (not therapeutic) doses can cause bundle branch blocks. Digoxin is very well known to cause conduction abnormalities when in toxic levels.

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

Is repetitive drug use the cause of a bundle branch block?

Is repetitive drug use the cause of a bundle branch block?

Depends, of course: Most cases of bundle branch block are due to a focal injury to a key part of the heart's electrical conduction system. Coronary disease, scarring from trauma, infection, or natural processes can cause it. Some illicit drugs, especially those creating coronary spasm (e.g., cocaine, amphetamines) may create those conditions, and frequent exposure (repetitive) only exacerbates the risk.

Can Lexapro (escitalopram) cause a right bundle branch block? If so, will it return to normal after stopping the medication?

Can Lexapro (escitalopram) cause a right bundle branch block? If so, will it return to normal after stopping the medication?

Not likely: Escitalopram does not cause rbbb, but it can cause irregularities of rhythm in rare individuals. If you're having side effects using lexapro, (escitalopram) see your doctor for alternatives or dosage adjustments.

Ar there medications to avoid when pt has a bundle branch block?

Avoid vs minimize: There are several GROUPS of drugs we would not use or use at very low doses with extreme caution, including but not limited to beta blockers, some calcium channel blockers, some anti arrhythmia drugs (actually most of them), among others

What are causes of left bundle branch block?

What are causes of left bundle branch block?

Various causes: Left bundle branch block is a pattern seen on an EKG indicating an abnormal or different pathway of the electrical signal that causes the heart muscle to contract. It is most often due to an underlying medical condition such as hypertension, a heart attack, an enlarged heart from any cause and only when serious conditions are excluded is it felt due to the benign aging of the conduction pathway.

What are causes of right bundle branch block?

What are causes of right bundle branch block?

Many: It can be congenital. It is often present with right ventricular or right atrial pressure or volume overload such as occurs with atrial or ventricular septal defect. Hypertension causes many cases. Pulmonary artery hypertension, as occurs in advanced lung disease or pulmonary embolism, can cause it. Finally, it's present in many healthy people for no reason at all.

Can chemotherapy cause left bundle branch block?

Can chemotherapy cause left bundle branch block?

Sometimes: A left bundle branch block is a finding on an EKG (the electrical tracing of your heart.) it shows that something has altered the way your heart conducts electrical impulses. Chemotherapy can do it, but so can heart disease. Your doctor should rule out other causes for a left bundle branch block before assuming chemotherapy is the cause.

Can JRA cause right bundle branch block às an adult?

Can JRA cause right bundle branch block às an adult?

Heart disease & RA: Perhaps. There are many heart disease manifestations seen in rheumatoid diseases. Best to have a conversation and evaluation with your primary provider. A Cardiology consultation would also be a good idea.

Does repetitive drug use take a toll on a persons heart sothey develop a bundle branch block?

Does repetitive drug use take a toll on a persons heart sothey develop a bundle branch block?

Maybe: It is possible depending on the type of drug used - a bundle branch block shows a decreased conduction of electrical impulses through the wiring of your heart.

Is left bundle branch block caused by rheumatic fever as a child?

Perhaps: Rheumatic fever and rheumatic heart disease refers to what we call a pancarditis. That means that the entire heart is playing in this condition. That's why we take strep infection so seriously. And yes I left bundle branch block can occur but is not the most common occurrence when someone has rheumatic heart disease or rheumatic fever.

What can cause a new left bundle branch block in a teen athlete? And can stress and anxiety maybe cause it?

What can cause a new left bundle branch block in a teen athlete? And can stress and anxiety maybe cause it?

There are a number: Of possibilities including EKG read incorrectly, newly recognized rather than new, Lyme disease, Viral cardiomyopathy. Stress and anxiety will not cause it. It would be appropriate to see a pediatric cardiologist for more evaluation.

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

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.

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.

I have an incomplete right bundle branch block is it dangerous nd can cause a cardiac arrest?

I have an incomplete right bundle branch block is it dangerous nd can cause a cardiac arrest?

Irbbb usually safe: Irbbb is usually an ECG anomaly that may speak of some right sided enlargement or strain (can occur in atrial septal defect or in pulmonary processes with right heart strain). It can also occur innocuously and unrelated to cardiac structural changes. It does not typically imply impending conduction system collapse and is not a predictor for cardiac arrest or sudden cardiac death.

I had ekg, nuc stress test, and angiogram. Was told I have left bundle branch block could this be cause of arrythmia and cause no other problems?

Possibly: You did not say if you were having symptoms (dizziness, palpitations, fainting, chest discomfort). Left bundle branch block is not an arrhythmia, but an abnormality in the heart's "wiring." it needs to be observed, but with normal tests as you described, and at your age, absent a family history of heart disease or sudden death it's unlikely to be dangerous at this time.

I was diagnosed with a right bundle branch block in 2014. My new doctor prescribed Flexeril for back pain. Is this medication safe for me to take?

Right bundle branch: I would highly recommend that you consult with your cardiologist befor taking this medication.
When you see your cardiologist next have him give you a list of medications that are contraindicated with your heart condition

What is a bundle branch block?

Wiring: The heart is a muscle but how fast it beats is controlled by special cells, sort of like electric wiring. The main wire divides into two, one to the right and one to the left. If part of that wiring becomes abnormal you get a right or left bundle branch block. It results in a typical pattern on the ekg.
