Predictors of High Defibrillation Threshold in the Modern Era

High defibrillation threshold (DFT) is a clinical problem in 1–8% of implantable cardioverter‐defibrillator implants. Some clinicians and investigators question whether the benefits of routine DFT testing outweigh the risks. Identification of the predictors of elevated DFT may allow selective application of DFT testing. However, the clinical characteristics of patients with high DFT in the modern era have not been well‐defined.
