WebNov 9, 2024 · As a result of several studies, DFT is today mostly omitted during TV-ICD implantation. However, DFT testing in S‑ICD implantation still has a class I indication, because of the extrathoracic position of the leads and the associated higher energy needed to convert VA . Quast ... the percentage of patients with a successful DFT test was 99.8%. WebThe use of epicardial defibrillation coils for ICD/CRT-D is a feasible treatment option for patients with either failed or contraindicated transvenous ICD systems. ... Device-related complications requiring a surgical/percutaneous revision or another DFT test occurred in six patients (54%). One patient died during follow up due to refractory ...
Defibrillator Threshold Testing - IntechOpen
WebJul 25, 2024 · Defibrillation threshold (DFT) testing is an integral part of implantable cardioverter-defibrillator (ICD) implantation. The primary functions of defibrillation assessment are to confirm appropriate sensing of ventricular fibrillation and to establish an adequate safety margin for defibrillation. WebAug 6, 2012 · A study of 50 consecutive patients with a dual-coil ICD lead and active can, underwent formal DFT testing at implant with the SVC coil programmed on or off in random order (mean DFT 8.7 joules ±4.0 in dual-coil configuration, versus 10.1 joules±5.0 in the single coil configuration). 3 A randomized study in 76 patients from 2003 demonstrated ... shares bnp
