heart block

n.
A condition in which faulty transmission of the impulses that control the heartbeat results in a lack of coordination in the contraction of the atria and ventricles of the heart.

heart block

n
(Pathology) impaired conduction or blocking of the impulse that regulates the heartbeat, resulting in a lack of coordination between the beating of the atria and the ventricles. Also called: Adams-Stokes syndrome or atrioventricular block
