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.
Arrhythmias and conduction disorders are caused by abnormalities in the generation or conduction of these electrical impulses or both. Any heart disorder, including congenital abnormalities of structure (eg, accessory atrioventricular connection) or function (eg, hereditary ion channelopathies), can disturb rhythm.
