Rapid Decline in Acute Stimulation Thresholds with Steroid‐Eluting Active‐Fixation Pacing Leads

Abstract

Active-fixation leads are commonly associated with initially high thresholds that fall rapidly. An initial threshold of 2 V should be provisionally accepted and retested at 4 minutes. The majority will have a threshold of <1 V the following day. A failure of a high threshold to decline at 4 minutes requires lead repositioning.
