conduction block

This term is a specialized medical descriptor used primarily in cardiology and neurology to describe a physiological failure in electrical signaling. It carries a clinical, objective tone and is typically found in diagnostic reports or medical textbooks rather than casual conversation.

Because it refers to a specific pathological state, it is often modified by adjectives such as "complete," "incomplete," or "first-degree" to specify the severity of the impulse failure. It describes a functional interruption rather than a physical blockage like a clot.
