Question

Quizplus · Accepted Answer

Heart block refers to a condition where the electrical impulse that controls heartbeat is delayed or blocked as it travels from the atria to the ventricles. This delay or block can occur at different points in the pathway, but most often it is at the AV node. Damage to the SA node or AV valves would not typically cause heart block, and damage to the AV bundle can cause heart block but it is less common than when it occurs in the AV node.
