| Abstract | efibrillation threshold (DFT) testing is an integral part of mplantable cardioverter-defibrillator (ICD) placement and ollow-up. Unfortunately, the DFT can vary widely from ay to day, influenced by many factors including electroytes, sympathetic tone, antiarrhythmic drugs, and other edications. For this reason, a 10-J safety margin between he lowest successful defibrillation energy during testing nd the maximal device output has been widely adapted as tandard practice. Analysis of 1,139 patients undergoing DFT testing after CD placement or revision at our institution demonstrated hat 6.2% had unacceptably high DFTs. Although the maority of these patients were undergoing initial ICD placeent, 37% were undergoing device revision, replacement, r upgrade. Unfortunately, a significant percentage of paients with high DFTs die of sudden cardiac death, presumbly due to inadequate defibrillation energy. In experienced ands, more than 85% of these patients can undergo system odification that provides adequate safety margins. In this rticle, we discuss therapeutic strategies to help manage atients with high DFTs. |
