Hi, I have gone through your query and understand your concerns.
When you have the LBBB of patterns on the EKG, usually a physical exam is adequate to determine whether you have an abnormality of the heart or not. It is necessary to obtain an echocardiogram to look at the cardiac structures.
You should check whether your LBBB is associated with: Coronary artery disease (CAD), Heart failure (HF), especially congestive heart failure (CHF), thickened, stiffened or weakened heart muscle (
cardiomyopathy) and
High blood pressure (hypertension). Also the a
bundle branch block, which are similar whether the blockage is on the right or left side of your heart, may develop some complications, such as slow heart rate (bradycardia, may need to have a pacemaker), arrhythmia or
cardiac arrest or
sudden cardiac death. In general, people who have a heart attack and develop a bundle branch block have a higher chance of complications and death than do people who have heart attacks and don't develop a bundle branch block.
According to your conditions, you should see your cardiologist to rule out above heart diseases even your
ejection fraction is 65% (normal range 55–70%). If you are associated with the diseases, you should obtain this type of treatment, which includes the following types of medications, thin your blood, slow your heart down, so that less demand matches limited blood supply, relax (dilate) your arteries so that more blood can pass through a wider pathway, lower your blood pressure so that the heart has to work less, modify your cholesterol to control the build-up of plaque (blockage), It also includes lifestyle modifications (diet, exercise and weight loss, smoking).
Now you are on Imdur treatment. You should know Imdur oral precautions, for example, anemia, low blood pressure, loss of too much body water (dehydration), and other heart problems. Because this drug may make you dizzy (do not drive). Older adults may be more sensitive to the side effects of this medication, especially dizziness and
lightheadedness, which could increase the risk of falls.
Once you are under correct direction and medicines, you will overcome your fatigue.
Wish you good health.
