Question 1

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.

Question 2

can left bundle branch block cause cardiomyopathy?

Accepted Answer

No relationship: A LBBB does not necessarily cause a cardiomyopathy however, individuals with cardiomyopathy frequently have a lbbb.

Question 3

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

Accepted 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.

Question 4

is left bundle branch block caused by rheumatic fever as a child?

Accepted 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.

Question 5

is heart block the same as rate related left bundle branch block?

Accepted Answer

Heart block and LBBB: Left bundle branch block is a form of arrhythmia or "heart block" as you mentioned. "heart block" would refer to all rhythm abnormalities, whereas left bundle branch block is a more specific type of arrhythmia.

Question 6

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 7

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 8

does right or left bundle branch block cause accelerated idioventricular rhytym?

Accepted Answer

: Although bundle branch blocks are not characterized by an association with an accelerated idioventricular rhythm, in an individual case, the two could be associated with one another.
This question can best be answered by an Electrophysiologist (a Cardiologist specialized in the characterization, cause and treatment of cardiac arrhythmias).

Question 9

can adderall, taken legally at prescribed dose, cause a left bundle branch block in a young person?

Accepted Answer

Cardiac risks:  I am not aware of a LBBB being cause by Adderall.  However, pt's with long  or shorQT syndrome,  hypertrophic cardiomyopathy, past arrhythmia requiring resuscitation, direct current cardioversion or defibrillation, or overdrive pacing; hx of arrhythmia associated with death or sudden cardiac death are at higher risk with Adderall.  For more  info see:  www.aafp.org/afp/2009/0515/p905.html

Question 10

how is accelerated idioventricular rhythm treated if it is caused by a right or left bundle branch block?

Accepted Answer

: An idioventricular rhythm is typically the result of a complete heart block, I would recommend urgent follow-up with a cardiologist to discuss treatment considerations
