| exit block | Inability of an impulse to leave its point of origin, the mechanism for which is conceived as an encircling zone of refractory tissue denying passage to the emerging impulse. (05 Mar 2000) |
|---|---|
| fascicular block | A condition based on the concept that the left branch of the bundle of His provides two of three major fascicles of a system of conduction, of which the right bundle branch constitutes the third, for the transmission of the cardiac impulse from the atrium above to the ventricles below the A-V node; block may occur in any or all fascicles, all three together producing complete A-V block. See: hemiblock. (05 Mar 2000) |
| unidirectional block | Block that prevents passage of an impulse when it approaches from one direction but not from the other, as when block in the A-V node prevents anterograde conduction to the ventricles while retrograde conduction to the atria remains intact. (05 Mar 2000) |
| field block | Regional anaesthesia produced by infiltration of local anaesthetic solution into tissues surrounding an operative field. (05 Mar 2000) |
| field block anaesthesia | Conduction anaesthesia in which small nerves are not anaesthetised individually, as in nerve block anaesthesia, but instead are blocked en masse by local anaesthetic solution injected to form a barrier proximal to the operative site. (05 Mar 2000) |
| first degree A-V block | See: atrioventricular block. (05 Mar 2000) |
