Can Certain Medications Cause Bundle Branch Block
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
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.See 1 more doctor answer
Can Lexapro (escitalopram) cause a right bundle branch block? If so, will it return to normal after stopping the medication?
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.See 1 more doctor answer
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.See 1 more doctor answer
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.See 1 more doctor answer
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.
See details: Nothing needs to be done. However, I would recommend a cardiology opinion.
What can cause a new left bundle branch block in a teen athlete? And can stress and anxiety maybe cause it?
I was told by my cardiologist I have right bundle branch block; there was no cause for concern. Can condition worsen? Can rbbb worsen?
Generally not: This is the most common "abnormal" ECG finding seen in otherwise "normal" patients.See 1 more doctor answer
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.
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.See 1 more doctor answer
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.See 1 more doctor answer
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.See 1 more doctor answer
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
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.See 1 more doctor answer
