brain-computer interface (BCI) Brain-computer interface (BCI) is a collaboration between a brain and a device that enables signals from the brain to direct some external activity, such as control of a cursor or a prosthetic limb. The interface enables a direct communications pathway between the brain and the object to be controlled.
If the QRS complex is wider than 0.12 seconds this is mostly caused by a delay in the conduction tissue of one of the bundle branches: 1  Left Bundle Branch Block (LBBB)) 2  Right Bundle Branch Block(RBBB) 3  Intraventricular conduction delay.
Sometimes both bundle branches are affected, and the bundle branch block pattern on the ECG is not clearly identifiable as either right or left bundle branch block. In this case, the bundle branch block is referred to as an intraventricular conduction delay.
