abstract

  • Although modern implantable cardioverter defibrillators (ICDs) can sense malignant ventricular arrhythmias, sudden death may occur from shock failure. Risk factors for high defibrillation thresholds (DFTs) have been identified. Patients may be at risk for ineffective defibrillation unless system modifications lower the DFT. The most common implant criterion (limited testing 10. J below the maximal output of the device) is imprecise in measuring the safety margin of ICDs and may not predict clinical outcomes. This article suggests preservation of DFT testing, particularly in patients at risk for high DFTs, and investigation into safe testing protocols that improve prediction of clinical outcomes. © 2011 Elsevier Inc.
