May prompt closer R-wave monitoring with downsized leads; leaves open long-term failure risk.
The Medtronic Sprint Fidelis ICD lead is associated with frequent abnormal R-wave sensing and a 2.8% lead revision rate in the first year, highlighting potential safety issues with downsized ICD leads.
Kenigsberg et al. (2007) studied this question.
