DF-1 connector
Pronunciation: DEE-eff-one
Also written as: DF-1 — Defibrillation-1
Industry-standard high-voltage connector for defibrillation leads, larger than IS-1 connectors to handle shock delivery.
Full Definition
A standardized connector system specifically designed for high-voltage defibrillation leads used with ICDs and CRT-D devices. The DF-1 connector is larger in diameter than the IS-1 connector used for pacing leads, as it must accommodate the higher voltage and current requirements for defibrillation therapy. This connector standard ensures compatibility between defibrillation leads from different manufacturers and ICD pulse generators that accept DF-1 connections.
Usage
Usage note: Always hyphenate and capitalize; distinguish from IS-1 pacing connectors.
