Can Chemotherapy Cause Left Bundle Branch Block
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 moreSee 1 more doctor answer
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
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 moreSee 1 more doctor answer
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 moreSee 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. ...Read more
What can cause a new left bundle branch block in a teen athlete? And can stress and anxiety maybe cause it?
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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
