Definition of Atrioventricular block

1. Noun. Recurrent sudden attacks of unconsciousness caused by impaired conduction of the impulse that regulates the heartbeat.




Medical Definition of Atrioventricular block

1. A conduction disturbance that results in the inappropriate delay (or complete inability) of a electrical impulse, generated in the atria, to reach the ventricles (via the atrioventricular node). Clinical types are divided into first (nonserious), second and third degree (most serious). Some drugs may precipitate atrioventricular block (for example clonidine, methyldopa, verapamil). A permanent pacemaker may be required for a third degree (complete) heart block. (02 Jan 1998)
