conductive lead fracture
Break in the electrical conductor within a pacing lead that maintains structural integrity but loses electrical continuity.
Full Definition
Conductive lead fracture represents a specific type of lead failure where the outer insulation remains intact but the internal conductor wire breaks, resulting in loss of electrical connectivity without visible external damage. This phenomenon creates unique diagnostic challenges and requires precise terminology in medical documentation, as it differs from insulation failures or complete mechanical fractures. Medical editors must distinguish this condition from other lead malfunctions when reviewing device complication studies and failure analysis reports.
Usage
Usage note: Specify 'conductive' to distinguish from other types of lead fractures; important for accurate adverse event reporting.
