Depends, of course: Most cases of bundle branch block are due to a focal injury to a key part of the heart's electrical conduction system. Coronary disease, scarring from trauma, infection, or natural processes can cause it. Some illicit drugs, especially those creating coronary spasm (e.g., cocaine, amphetamines) may create those conditions, and frequent exposure (repetitive) only exacerbates the risk.
