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.
Most patients with left ventricular hypertrophy and coronary artery disease of LAD show left bundle branch block (LBBB) conduction delay pattern on the surface electrocardiogram (ECG). 1  Alcoholic cardiomyopathy. 2  Aortic insufficiency. 3  Aortic stenosis. 4  Cardiomyopathy. Chagas disease.  Coronary heart 1  disease. Cushing's syndrome.  Digoxin toxicity.
