Unfortunately, LBBB cannot be reversed. In your instance, the total risk of cardiovascular morbidity or mortality should be quite minimal in the absence of significant structural heart disease and symptoms. In people with LBBB, the main concern is not whether or not they will develop heart failure. Instead, the risk is that the abnormal rhythm pattern may lead to electrical disturbances within the heart that can cause other problems such as double-blocked arteries, reduced blood flow to the legs, and even sudden death. In general, individuals with LBBB have very few complications from the condition. However, if you are at high risk for cardiovascular events, doctors may recommend treatment to reduce this risk. For example, patients with LBBB who are also diagnosed with hypertension or diabetes may require medication to control these conditions. People with LBBB may experience symptoms of heart block during exercise or emotional stress. If you are experiencing any of these symptoms, talk with your doctor about possible ways to manage them. LBBB does not affect the overall length of your life but it can lead to serious complications if proper treatment is not administered promptly. So if you are a patient with LBBB, make sure to speak with your doctor about any future plans you have so they can give you appropriate guidance.
