      Abstract

      The 2015 HRS/EHRA/APHRS/SOLAECE Expert Consensus Statement on Optimal Implantable Cardioverter-Defibrillator Programming and Testing provided guidance on bradycardia programming, tachycardia detection, tachycardia therapy, and defibrillation testing for implantable cardioverter-defibrillator (ICD) patient treatment. The 32 recommendations represented the consensus opinion of the writing group, graded by Class of Recommendation and Level of Evidence. In addition, Appendix B provided manufacturer-specific translations of these recommendations into clinical practice consistent with the recommendations within the parent document. In some instances, programming guided by quality evidence gained from studies performed in devices from some manufacturers was translated such that this programming was approximated in another manufacturer’s ICD programming settings. The authors found that the data, although not formally tested, were strong, consistent, and generalizable beyond the specific manufacturer and model of ICD. As expected, because these recommendations represented strategic choices to balance risks, there have been reports in which adverse outcomes were documented with ICDs programmed to Appendix B recommendations. The recommendations have been reviewed and updated to minimize such adverse events. Notably, patients who do not receive unnecessary ICD therapy are not aware of being spared potential harm, whereas patients in whom their ICD failed to treat life-threatening arrhythmias have their event recorded in detail. The revised recommendations employ the principle that the randomized trials and large registry data should guide programming more than anecdotal evidence. These recommendations should not replace the opinion of the treating physician who has considered the patient’s clinical status and desired outcome via a shared clinical decision-making process.

      Manufacturer-Specific Translation of ICD Programming Recommendations
      The manufacturer-specific programming settings/choices set forth below are based on a compilation of clinical expertise and clinical trial data as reported in the 2015 HRS/EHRA/APHRS/SOLAECE Expert Consensus Statement on Optimal Implantable Cardioverter-Defibrillator Programming and Testing, of which this Appendix B is a part. These recommended settings/choices represent a diligent and good faith effort on the part of the writing committee to translate the consensus statement recommendations to device settings/choices for the four specified clinical issues/implantable cardioverter-defibrillator (ICD) therapies where the writing committee considered that there was sufficient consensus and supporting data to make recommendations intended to improve the safety, morbidity, and mortality profile of patients with these clinical issues/ICD therapies. They are the recommendations of the writing committee only. They do not represent the position or recommendations of HRS, EHRA, LAHRS (formerly SOLAECE), or APHRS, nor are they the manufacturer’s nominal settings or the precise programming tested during clinical trials of these devices, nor are they necessarily the settings/choices that would be recommended by the manufacturer. These recommended settings/choices are not applicable in all circumstances. As stated in the Introduction to the consensus statement, “The care of individual patients must be provided in context of their specific clinical condition and the data available on that patient.” Each treating physician must carefully consider the circumstances of their individual patient and determine whether these recommended settings/choices are appropriate to their patient’s circumstances.

      1 Fewer intervals to detect may be reasonable due to the possibility of VT straddling 2 zones that may result in “binning” to both zones, effectively doubling time to detect. Beats that fall out of zone sometimes reset counters so patients with poor sensing should also have fewer detection intervals considered.

         In patients where VT CL is known

      • VF:
        20 cycle* + 6/8 majority >255bpm*
      • FVT:
        20 cycle*+ 6/8 majority 230bpm

      Therapy
      • VF:
        6 x 42J*
      • FVT:
        If stable2: 1 x ATP (Burst @ 85% x 8 beats) then 6 x 42J* (unless DFT guided)
      • If unstable: 6 x 42J* (unless DFT guided)
      • VT:
        ≥1 x ATP (Burst + Scan @ 85% x 8 beats; Scan 8ms) then all Shocks ON*3
      2 Satisfaction of stability (nominal value = 30ms) in the Fast VT zone will not prevent therapy but rather activate programmable burst pacing prior to shock therapy.

      3 Rarely, hemodynamically stable slow VT can be treated without programming a back-up shock.
      SVT Discriminators4

         Single Chamber

      • Single button programming; Stability+/Acc
      • Rate, Stability, Degree of Onset, VT long cycle search
      • Nominal settings: Onset 19%, Stability 65ms (Slow VT, VT); Long cycle extension 10 cycles; Long cycle gap 170ms

         Dual Chamber/CRT-D

      • Single button programming; PARAD+
      • Rate, Stability, AV association analysis, Degree and Chamber of Onset, VT long cycle search
      • Nominal settings: Onset 25%, Stability 65ms (Slow VT, VT); Long cycle extension 10 cycles; Long cycle gap 170ms
      4 SVT Discriminators are not required in Complete Heart Block.
      Oversensing Rejection
      • Daily check Lead impedance ON*
      • Daily check Lead coil continuity ON*
      • Daily check V oversensing alerts ON*
      • T-wave filtering and noise detection are hardcoded in firmware
