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

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

What occurs when someone has right bundle branch block?

What occurs when someone has right bundle branch block?

Not much: Bundle branch block happens when there is a delay in conduction across a bundle. The his purkinjie fibers break into lb and rb. When there is a block in the rb, it is called rbbb. In most cases rbbb is of minimal consequence. ...Read more

What is an incomplete right bundle branch block in the heart?

What is an incomplete right bundle branch block in the heart?

Electrical slowing: The conduction of electricity in the lower chambers of the heart occurs through the left and right bundles. An incomplete right bundle branch block is an insignificant finding, representing a slight slowing in the electrical conduction as it passes through the right side of the heart. Please be aware that this has nothing to do with blockages in the arteries or heart attacks. ...Read more

I have an incomplete right bundle branch block is it dangerous nd can cause a cardiac arrest?

Irbbb usually safe: Irbbb is usually an ECG anomaly that may speak of some right sided enlargement or strain (can occur in atrial septal defect or in pulmonary processes with right heart strain ). It can also occur innocuously and unrelated to cardiac structural changes. It does not typically imply impending conduction system collapse and is not a predictor for cardiac arrest or sudden cardiac death. ...Read more

What does it mean to have an incomplete right bundle branch block?

What does it mean to have an incomplete right bundle branch block?

Not much: It is a benign EKG finding related to a slight delay in the conduction system (like electrical wiring) of the heart. It is more common in those with an atrial septal defect (hole between left and right heart) but in general is benign, nothing to worry about. ...Read more

Is a block in the right bundle branch serious?

No: Millions of people have rt bundle blocks, heart function remains normal. As you age, other conduction issues may arise, and of course blood vessel disease, etc. ...Read more

What is a right bundle branch block?

What is a right bundle branch block?

Abnormal conduction: The signal to beat is distributed to through the heart by a specialized electrical system. The right bundle is one of the branches of this system. If conduction through the right bundle is slowed or blocked the parts of the heart it serves will contract late, seen as widening of the electrocardiographic qrs-wave. Unless the remainder of the conduction system fails, it usually isn't a problem. ...Read more

What is a sinus rhythm with a right bundle branch block?

What is a sinus rhythm with a right bundle branch block?

Wiring of heart: Sinus rhythm means that the electrical activity that controls the contraction of the heart, starts in the sinus node. Right bundle branch block means that the right bundle (part of the electrical wiring) does not conduct the impulse which changes the appearance of the ekg. Right bundle branch block as opposed to left bundle branch block is usually benign. ...Read more

Is a right bundle branch block serious? I have a history of SVT, thanks!

Is a right bundle branch block serious?  I have a history of SVT, thanks!

No: Generally RBBB is not serious - it can even be present from birth. With your hx of SVT, there are certain abnormalities that need to be considered and excluded: atrial septal defect and mitral stenosis. Lung conditions can cause it. Sometime high blood pressure is the cause. There are rare causes too, but in most cases, it's an isolated finding of no significance. In itself RBBB causes no symptoms ...Read more

What is the connection between right bundle branch block with slow heart beat?

What is the connection between right bundle branch block with slow heart beat?

It depends: Right bundle branch block(rbbb) in itself is usually a benign disturbance of conduction system of the heart. It usually does associated with adverse effects. However, it may be a part of other serious conduction disorders of heart (like high degree av block). Therefore, it may not be the cause of but a part of findings in a slow heart rate. Also remember, slow heart rate is not always bad. ...Read more

An ECGinterprets RIGHT BUNDLE BRANCH BLOCK, LEFT POSTERIOR FASCICULAR BLOCK, BIFASCICULAR BLOCK. I dont' feel any dizziness. Is it normal?Cure for it?

Not normal: Those findings on EKG are not normal, and are permanent. They can be caused by defects in the conduction system of the heart that you have had since birth, by previous heart attacks, or remodeling of the heart in response to ongoing hypertension. You should consult with a cardiologist for further evaluation. ...Read more

I have been diagnosed with a right bundle branch block of the heart. Can I reverse this?

I have been diagnosed with a right bundle branch block of the heart. Can I reverse this?

Probably not: A right bundle branch block is either slowed or blocked conduction in one of the three fascicles ("wires") that connect the top chambers to the bottom chambers of the heart. Generally speaking, if the right bundle block has been there a while, it'll stay. Sometimes they come and go, but that's like an extension cord on the fritz and sparking. Good news: you'll be fine with just the left bundle. ...Read more

Can i overcome the incomoplete right bundle branch block?

No need: You don't need to and cannot reverse rbbb (incomplete or complete). Many normal people are born with it. It causes no symptoms and is not indicative of disease. There is no treatment indicated or necessary. ...Read more
