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.
What causes non-specific ST-T wave abnormalities? A: Non-specific ST-T wave abnormalities can be caused by digitalis effect, myocardial ischemia, hypokalemia, left ventricular hypertrophy with strain and reciprocal changes from an ST elevation myocardial injury. Getting an electrocardiograph test will help diagnose the problem. Continue Reading.
