Question 1

is left bundle branch block reversible?

Accepted Answer

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.

Question 2

how do you treat left bundle branch block?

Accepted Answer

Treatment of LBBB: There is no specific treatment for left bundle branch block. However, treatment is directed at the underlying cause of this conduction disturbance.

Question 3

what are causes of left bundle branch block?

Accepted 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.

Question 4

is left bundle branch block life shortening?

Accepted Answer

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.

Question 5

will left bundle branch block cells regenerate?

Accepted Answer

No: The bundle branch may stop functioning due to age related cell death or some other process which damages the heart. Sometimes patients have intermittent bundle branch block. This may be related to the heart rate. The bundle branch does not regenerate.

Question 6

what is left bundle branch block is characterized by?

Accepted Answer

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.

Question 7

what occurs when someone has a left bundle branch block?

Accepted 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.

Question 8

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

Accepted Answer

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.

Question 9

is there a cure for a left bundle branch block?

Accepted Answer

Bundle branch block: A left bundle branch or LBBB is a slowing of conduction in the left bundle of the conduction system to the left ventricle. It may be a sign of underlying problems ie coronary artery disease or electrolyte abn. Or may be from congenital heart dz. There are many causes and your ans. Would depend on the cause . Sometimes its just a matter of close observation and treating risk factors.

Question 10

can chemotherapy cause left bundle branch block?

Accepted 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.
