Bundle branch block is a condition where there is a delay or obstruction of the electrical impulse going to the heart. It can happen in the signals going to the right or the left side of the heart. There is no direct treatment of bundle branch block, rather it is important to look for the causes and treat those. Atherosclerosis (blockage of blood vessels) congestive heart failure or hypertension can be factors causing right bundle branch block and all of these are treatable.
If you have been diagnosed with this condition, a full cardiac evaluation is essential.
