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

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

Can smoking marijuana have bad effects for a left bundle branch block?

Can smoking marijuana have bad effects for a left bundle branch block?

Maybe yes: Among the bad things smoking marijuana does to the heart and lungs are the quick 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

What occurs when someone has a left bundle branch block?

What occurs when someone has a left bundle branch block?

Nothing to severe: Left bundle branch block (lbbb) is a pattern on the ECG that indicates that the heart's electrical waves are following an unusual path. It is common in older age, and usually due to scarring of the pathway. It may cause no symptoms and need no therapy. It can lead to marked slowing that needs a pacemaker. A new LBBB can also be a sign of a heart attack. ...Read more

Is there a cure for a left bundle branch block?

Is there a cure for a left bundle branch block?

Cure?: "cure" suggests that LBBB is a disease but it is not. It is associated with underlying structural heart disease and that is what should be addressed. Lbbb causes no symptoms and it requires no treatment. ...Read more

I hear my heartbeat in my head. I just find out I have a left bundle branch block. Had a heart cat everything fine. Why do I hear this sometimes?

I hear my heartbeat in my head. I just find out I have a left bundle branch block. Had a heart cat everything fine. Why do I hear this sometimes?

Rule out murmue: Some forms of heart murmurs could cause the symptoms you are describing and can be detected on an echocardiogram which you've likely had. This could also be a form of tinnitus that can be evaluated by an ENT. Hope it goes away. ...Read more

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. ...Read more

What are differences between left bundle branch block and right bundle branch block?

What are differences between left bundle branch block and right bundle branch block?

The location: Obviously the location of the electrical block in the conduction of electric impulses from the atrium to the ventricles is different. The electrical signals travel to the two ventricles through the left and the right bundle, the left then bifurcates to two fascicles itself. In my experience, the non-pathologic presence of right bundle branch block is more common. ...Read more

Can you drink alcohol with left bundle branch block?

Can you drink alcohol with left bundle branch block?

Depends: Depends on what caused the LBBB (congenital or after a heart attack), and how much you are drinking. Alcohol in low doses (1-2 drinks/day in men, 1 drink/day in women and older men) is often considered a tonic for the heart and raises "good cholesterol." in higher doses, it can damage the heart, raise blood pressure and cause heart rhythm problems. Talk to your internist or cardiologist about it. ...Read more

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 am 21, what can left bundle branch block mean on my EKG? It shows up whether my HR is normal or fast

Rate related delay: You have a "rate related LBBB" meaning that as your heart speeds up, the conduction through the His-Purkinje network of fibers (conducting tissue in the heart muscle) take a longer time than normal to repolarize (prepare electrically for the next impulse). As I said in my previous post to you, trust your EP doctor. ...Read more

Will left bundle branch block cells regenerate?

Will left bundle branch block cells regenerate?

Usually not: Left bundle branch block (lbbb) develops when 2/3 electrical "wires" in the heart stop working. Many patients can have LBBB and no sx. Lbbb usually reflects aging of the heart but can be seen in a variety of pathological heart conditions. Rarely, medicines which affect the speed of electrical conduction in the heart can cause LBBB which reverses. This technically not cellular regeneration. ...Read more

What to do if I have a small left bundle branch block, will I be able to join the army as a 31b?

LBBB: LBBB is like pregnancy - You have it or you don't. You can't have a "small LBBB". (you could have an incomplete LBBB). Whether or not it disqualifies you would depend on the reason it's there, so you need a cardiac evaluation - usually consisting of, at least, an echocardiogram and stress test. ...Read more

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. ...Read more

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. ...Read more

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. ...Read more

Female age 45 have complete left bundle branch block for 7 yrs recently had mild hypokinesia CT angio result no block. What to worry? Effect of stress?

No worry: If the bundle branch block is not associated with coronary disease, it is generally not a big deal. A wall motion abnormality, typically septal hypokinesia, usually goes along with the conduction delay. ...Read more

Why does my EKG change every year? Sometimes says right bundle branch block and this time a left bbb. Can they go away on their own? I'm 43 female

Why does my EKG change every year? Sometimes says right bundle branch block and this time a left bbb. Can they go away on their own? I'm 43 female

No: So it is not common for ECG interpretation to vary that much, that is, one year RBBB and another year LBBB as the etiologies of the two are diffferent. In a young person, a new LBBB, merits an ischemic evaluation and medical followup. A RBBB is more benign. Could your ECGs have been misintepreted or are you sure they are yours? Also, sometimes a BBB can develop at different rates. Go see a cardiol ...Read more
