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

What is the survival rate with left complete bundle branch block?

What is the survival rate with left complete bundle branch block?

Depends: On the underling cause. Those with coronary artery diease or myocardial infarction have a much worse prognosis than an incidental lbbb.(left bundle branch block). ...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 dont 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 doesnt cause symptoms by itself. ...Read more

Is left bundle branch block reversible?

Is left bundle branch block reversible?

Yes: It is sometimes seen intermittently. It can be present on an EKG and not on one done at a later date. At times it occurs when the heart is beating fast but not with slower heart rates. ...Read more

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. ...Read more

Is left bundle branch block life shortening?

Is left bundle branch block life shortening?

Possibly: As most people with lbbb have heart muscle abnormalities, yes. But about 15% of people with left bundle branch block have structurally normal hearts, so the answer is maybe or sometimes. ...Read more

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 is left bundle branch block is characterized by?

What is left bundle branch block is characterized by?

Found on EKG: It is caused by a block in the "electrical wiring" of the heart which affects the appearance of the ekg. It most of the time indicates a significant problem with the heart but can at times be benign. ...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

If diagnosed with left bundle branch block & doing ok, will my insurance premiums be higher?

Can't answer...: No expert on insurance premiums (thank goodness ) but lbbb is not a benign diagnosis or "normal" variant so despite your well compensated or normal feeling state of health the insurers may see it differently...Sorry. ...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 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

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?

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

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
