Reassessing Risk Factors for High Defibrillation Threshold: The EF‐SAGA Risk Score and Implications for Device Testing

Abstract

We identified five independent predictors of high DFT. We propose the EF-SAGA risk score to help decision making. Primary prevention patients with an LVEF > 20% had an exceedingly low incidence of high DFT suggesting that testing could be avoided in these patients. Careful assessment of the risk-benefit ratio of testing is important in high-risk patients.
