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. What are causes of left bundle branch block?
Is there a cure for a left bundle branch block?
Other conditions that can cause a left bundle branch block include:
- coronary artery disease
- heart failure
- high blood pressure (hypertension)
- problems with the aortic valve
- heart infection ( myocarditis)
- weakened, enlarged, or stiffened heart muscle ( cardiomyopathy)
How do you treat left bundle branch block?
There are left bundle branch block risks. LBBB has been linked to hypertension, ventricular hypertrophy, valvular heart disease, myocarditis, ischemic heart disease, heart failure, as well as cardiomyopathies. The Framingham Heart Study indicated that LBBB was associated with seven times as great a risk of heart failure.
How serious is left bundle branch block?
Unfortunately LBBB is not reversible. In your case, in the absence of any structural heart disease and symptoms, the overall risk of cardiovascular morbidity or mortality should be very low. Which bundle branch block is worse? For most people, this is not a big problem.
Can left bundle branch block go away?
What treatment is given for left bundle branch block?
People with heart failure and left bundle branch block may need cardiac resynchronization therapy or CRT. This is a type of pacemaker therapy that helps the ventricles contract at the same time. CRT can increase the amount of blood that the heart ejects and can improve symptoms of shortness of breath and fatigue.
Does LBBB need treatment?
Most people with bundle branch block don't have symptoms and don't need treatment. For example, left bundle branch block is not treated with medications. However, treatment depends on your specific symptoms and other heart conditions.
Can left bundle branch block be improved?
Unfortunately LBBB is not reversible. In your case, in the absence of any structural heart disease and symptoms, the overall risk of cardiovascular morbidity or mortality should be very low.
Should I worry about left bundle branch block?
A left bundle branch block can signify a serious underlying heart condition, but not always. In people under 50 without other comorbidities, LBBB is typically benign. However, further testing is warranted if you have LBBB and other risk factors for cardiovascular disease.
Are beta blockers used for LBBB?
Painful LBBB Syndrome Proposed treatment options include beta-blocker therapy,67 CRT,36 and HBP.
Is exercise good for LBBB?
After three months of regular exercise training with 30-minute sessions per day for five days a week, the patient's symptoms improved with development of LBBB and chest pain at a considerably higher heart rate of 150 bpm (Figure 3).
What is life expectancy with LBBB?
The mortality rates were 4.5%/year for patients with LBBB, 2.5%/year for patients with RBBB, and 1.9%/year for patients without BBB (P < 0.001). Among patients with a normal SE, those with LBBB had similar mortality to those without LBBB (HR = 0.9; 95% CI: 0.4-2.2; P = 0.8).
Can left bundle branch block lead to heart failure?
Abstract. The prevalence of left bundle branch block (LBBB) is significantly higher in the heart failure (HF) population compared to the general population. LBBB is more often associated with structural heart disease especially dilated cardiomyopathy (DCM) of a non-ischemic origin.
Is a left bundle branch block considered heart disease?
A left bundle branch block usually is a sign of an underlying heart disease, including dilated cardiomyopathy, hypertrophic cardiomyopathy, high blood pressure, aortic valve disease, coronary artery disease and other heart conditions. While left bundle branch block can appear in healthy people, it most often does not.
Can stress cause a bundle branch block?
The incidence of exercise stress test-induced left bundle branch block (LBBB) is rare and reportedly occurs in approximately 0.5-1% of all patients undergoing exercise testing [1]. The mechanism is poorly understood, but ischemia is one of the proposed etiologies.
Does LBBB cause dizziness?
Symptoms of left bundle branch block But in some cases you may have symptoms such as: Dizziness. Fainting. Trouble breathing with physical activity.
Types of treatment
If you have no symptoms or other heart problems, you may not need treatment. If you have symptoms or other heart problems, you may need treatment such as:
Possible complications of left bundle branch block
People with no symptoms and no other heart problems are unlikely to have complications. In other cases, complications may include:
What is a left bundle branch block?
Left bundle branch block is a problem in the heart’s electrical system. The heart has 2 main nerves that cause the heart to contract. They are called bundle branches and they connect the top and bottom chambers of the heart. In left bundle branch block, the left bundle branch does not work properly causing the left lower heart chamber (ventricle) ...
What is the treatment for heart failure?
If you have no symptoms or other heart problems, you may not need treatment. If you have symptoms or other heart problems, you may need treatment such as: Pacemaker. A device is put into your chest to help your heart pump normally using wires placed in the heart. Cardiac resynchronization therapy (CRT).
What is the best way to treat LBBB?
If you have LBBB due to a heart attack, for example, you may need a pacemaker. This is a device that emits electricity to help your heart maintain a consistent rhythm. If you have high blood pressure, you may need to take medication to keep it under control. This will also reduce the strain on your heart.
What causes bundle branch block?
A variety of things can cause LBBB. For example, a heart attack can damage your heart tissue, making it harder for it to conduct electricity. This can result in bundle branch block at either the right or left ventricle.
How to diagnose LBBB?
Doctors usually diagnose LBBB by using an electrocardiogram (EKG). This is a painless test that involves placing stickers called leads around your chest. The leads conduct electricity. They’re connected to wires that sense the electrical impulses of your heart and trace your heart’s rhythm.
What is the bundle of his?
The bundle of His is an area of the heart that conducts impulses to the left and right ventricles. Left bundle branch block (LBBB) is a blockage of electrical impulses to the heart’s left ventricle. This is the lower-left portion of the heart.
Why does the electrical pattern bundle branch block?
Doctors call the resulting electrical pattern bundle branch block because the electrical impulse encounters a roadblock at the left or right branch of the “bundle of His.”.
Is LBBB serious?
LBBB can seem alarming, but they’re usually not as serious as they sound. In some cases, you might not even know you have one. If you have LBBB that needs treatment, your doctor will come up with a plan that addresses the underlying cause.
Do you need a pacemaker for LBBB?
If you do have another heart condition, your doctor might suggest treating the underlying cause. If you have LBBB due to a heart attack , for example, you may need a pacemaker.

What is left bundle branch block?
Left bundle branch block is a problem with the heart’s electrical wiring (conduction) system. Your heart has 4 chambers. The 2 upper chambers are called atria, and the 2 lower chambers are called ventricles. In a healthy heart, the signal to start your heartbeat begins in the upper right chamber of the heart (right atrium).
What happens when the right and left bundles of the heart are blocked?
When this happens, the impulses from the top chambers of the heart do not activate the lower chambers of the heart. This can lead to long episodes in which the heart stops.
What is the name of the bundle branch that sends electrical signals to the heart?
Two bundle branches carry the electrical signal to the bottom of the heart and cause the ventricles to beat. These are termed the right bundle and left bundle. In left bundle branch block, there is ...
What is the right bundle and left bundle?
These are termed the right bundle and left bundle. In left bundle branch block, there is a problem with the left branch of the electrical conduction system. The electrical signal can’t travel down this path the way it normally would. The signal still gets to the left ventricle, but it is slowed down. That's because the signal has to spread ...
What to do if you have a follow up appointment?
If you have a follow-up appointment, write down the date, time, and purpose for that visit.
Can you see your healthcare provider if you have a left bundle branch block?
Make sure you see your healthcare provider regularly, even if you don’t have any symptoms. Make sure all your health care providers know about your left bundle branch block. Be aware that left bundle branch block may make it harder for a healthcare provider to diagnose a heart attack.
Is left bundle branch block a risk factor for heart failure?
In older people with coronary artery disease, left bundle branch block is associated with greater risk of death. This is especially true for people with heart failure.
What causes left bundle branch block?
If there is a problem with the branch that sends the electrical signal to the left ventricle, this may interfere with the heart’s pumping activity and result in left bundle branch block.
