Question 1

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 2

hoping you can tell me, is right bundle branch block (rbbb) something to really stress over everyday?

Accepted Answer

Not really: Rt bbb is a common ekg finding and it may occur in some medical conditions.But it is also common in some people with normal heart
it occurs in conditionsthat effect the right ventricle or the lungs.If you are otherwise healthy and no other symptoms and your doctor gave you clean chit, than you do not need to stress over it every day.

Question 3

i was told by my cardiologist i have right bundle branch block; there was no cause for concern. can condition worsen? can rbbb worsen?

Accepted Answer

An : An isolated right bundle branch block can occur in people with no other heart disease, and may never worsen or cause you any trouble. Nothing needs to be done now. Isolated rbbb rarely progresses to complete heart block (rbbb and lbbb), but depending on other health conditions this is possible. Just be sure to let your doctor know if you develop anything like chest pain, shortness of breath, dizziness, or fainting.

Question 4

would a echocardiogram report a right bundle branch block? because it was normal, but my electrocardiogram did report a rbbb, false reading?

Accepted Answer

Right bundle branch: We share similar EKGs and I have no heart poblems.  According to a recent article in the European Heart Jounal the prevalence of RBBB that is normal variant is 4 percent for men and 2 percent for women.  RBBB does develop in people with lung problems, especially with COPD or Pulmonary embolus. It can develop in some people who have other processes that effect conduction.

Question 5

would it be possible that a rbbb (right bundle branch block) cause a heart murmur?

Accepted Answer

No: But there are conditions that can both cause a heart murmur and a rbbb (for example, pulmonic stenosis or  an atrial or ventricular septal defect).

Question 6

ecg: normal sinus rhythm, incomplete right bundle branch block, borderline ecg. dr said right bundle branch block related to my asthma so not worried about it. can someone explain what the rbbb and borderline ecg mean. thanks?

Accepted Answer

Conduction system : Right bundle branch block refers to a change in the electrical conduction system of heart. Can be related to stretching of the heart muscle or minor damage to that area of heart. As isolated finding it is not uncommon and doesn’t indicate any increased cardiac risk by itself.ECG read as borderline because other findings in addition to RBB might merit investigation if they appear on subsequent ECGs

Question 7

right bundle branch block and z-pack (azithromycin)  prescribed for infection. haven't taken yet, any concern for heart issues with rbbb and azithro?

Accepted Answer

BBB: ECG QT interval prolongation can be a concern with azithromycin,the bundle block adds to the measured QT interval ,however  the more relevant measure is the JT interval that ECG machines don't record/measure,consult locally with the prescribing physician.Also don't delay antibiosis with out the prescriber being aware.

Question 8

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 9

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 10

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.
