Is LBBB a serious heart condition?
LBBB is more serious if you have conditions such as heart failure, heart attack, hypertension, bacterial or viral infection of the heart muscle (myocarditis), or thickened, stiffened, or weakened heart muscle (cardiomyopathy).
Is LBBB congestive heart failure?
LBBB in the absence of a clinically detectable heart disease is associated with new-onset CHF and death from cardiovascular diseases. Further study is warranted to determine if additional diagnostic testing or earlier treatment in patients with asymptomatic LBBB can decrease cardiovascular morbidity or mortality.
Does exercise help 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). The morphology of the LBBB remained the same.
Can left bundle branch block be caused by stress?
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].
Is there any cure for left bundle branch block?
If a person with left bundle branch block has a heart attack, reperfusion therapy may be given to restore blood flow through blocked arteries. This can be done by using an anti-clotting agent, such as streptokinase, to dissolve blood clots and increase blood flow to the heart.
How serious is bundle branch block?
When right bundle branch block is detected, the chief concern should be to do an evaluation to look for an underlying cardiac or pulmonary condition. If no such condition is found, the right bundle branch block generally can be considered completely benign (not harmful).
How do you determine bundle branch block?
Diagnosing bundle branch block is straightforward. A 12-lead ECG will show the characteristic widening of the QRS complex, along with the characteristic pattern of right or left bundle branch block (or, in some cases, an intraventricular condition delay that cannot be characterized as either right or left bundle branch block).
How do you treat left bundle branch block?
However, if you have a heart condition causing bundle branch block, treatment might involve medications to reduce high blood pressure or lessen the effects of heart failure. Additionally, depending on your symptoms and whether you have other heart problems, your doctor might recommend: A pacemaker.
