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.
(duration of QRS complex in frontal plane): 1  Normal: 0.06 - 0.10s. 2  Prolonged QRS Duration (> 0.10s): QRS duration 0.10 - 0.12s Incomplete right or left bundle branch block. Nonspecific intraventricular conduction delay (IVCD) Some cases of left anterior or posterior fascicular block.
