There must be a prolonged S wave in leads I and V6 (sometimes referred to as a "slurred" S wave).The T wave should be deflected opposite the terminal deflection of the QRS complex. This is known as appropriate T wave discordance with bundle branch block. A concordant T wave may suggest ischemia or myocardial infarction. Treatment
The underlying condition may be treated by medications to control hypertension or diabetes, if they are the primary underlying cause. If coronary arteries are blocked, an invasive coronary angioplasty may relieve the impending RBBB. Epidemiology
Prevalence of RBBB increases with age due to changes in the hearts conduction system. Its estimated up to 11.3% of the population by the age of 80 have RBBB. Gallery

Management
When fat necrosis is being felt by a physician or patient, it may feel larger, smaller, unchanged, or not felt at all (resolved). Fat necrosis usually does not require surgery, it usually requires a patient to meet with their physician and as long as the pain is not present there is nothing to be concerned about unless the patient is concerned about cosmetic abnormalities. However, if pain is present surgery is a form of treatment a patient can consider. To keep track of benign fat necrosis a yearly mammogram is taken in order to observe it. However, if fat necrosis consists of oily fluid a physician will go in with a needle to remove this liquid, which may be causing discomfort. Excision may be needed if the mass becomes solid or causes a cosmetic abnormality. Prognosis
Although getting diagnosed with fat necrosis of any kind can be a great cause for concern, as most individuals may mistake it for a malignant tumor. Fat necrosis of the breast is a prognosis that is benign and does not increase an individuals risk for various cancers. An individuals life expectancy does not decrease with this diagnosis. Epidemiology
Fat necrosis in the breast occurs around 0.6%, this represents 2.75% of lesions that end up being benign. However, 0.8% of fat necrosis occurs from tumors of the breast, 1% - 9% occurs in breast reduction surgery. Individuals that are high risk include women around the age of 50yrs along with pendulous breasts.
