Left bundle branch block (LBBB) is a cardiac conduction abnormality seen on the electrocardiogram (ECG). In this condition, activation of the left ventricle is delayed, which causes the left ventricle to contract later than the right ventricle.
PBB refers to the billing process for services rendered in a hospital department or location. This is the national model of practice for large, integrated delivery systems where the hospital owns space and employs support personnel involved in patient care.BB refers to the billing process for services rendered in a hospital department or location.
