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

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

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 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

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
