Defibrillation thresholds testing of implantable cardioverter-defibrillators at implantation

Defibrillation thresholds testing of implantable cardioverter-defibrillators at implantation.

I read with interest the reports on defibrillation testing (DFT) during implantable cardioverter-defibrillator (ICD) implantation published recently in JACC (1,2). There is a significant, albeit low, risk to serious complications including death during DFT testing. If the implantation data as measured through the device are satisfactory, then should we induce ventricular fibrillation (VF) in a ...

Is defibrillation testing necessary for implantable transvenous defibrillators?: defibrillation testing is necessary at the time of implantable cardioverter defibrillator implantation.

Subcutaneous Implantable Cardioverter Defibrillators Implantation Without Defibrillation Threshold Testing: A Single Center Experience

Background Subcutaneous implantable cardioverter defibrillator (S-ICD) system has been proven to be an effective therapy for prevention of sudden cardiac death (SCD) in selected patients. Although the Shockless IMPLant Evaluation (SIMPLE) trial has shown that defibrillation threshold (DFT) testing is not necessary for transvenous ICD (TV-ICD) systems, it is still recommended for S-ICD systems. ...

Is defibrillation testing necessary for implantable transvenous defibrillators?: defibrillation testing should not be routinely performed at the time of implantable cardioverter defibrillator implantation.

B ecause the implantable cardioverter defibrillator (ICD) was introduced into clinical practice, insertion of these devices has typically involved defibrillation testing (DT). However, DT has never been shown to independently improve patient outcomes. The rationale for DT has always been that the induction of ventricular fibrillation (VF) immediately after ICD insertion allows the implanting te...

Azygos Vein Lead Implantation For High Defibrillation Thresholds In Implantable Cardioverter Defibrillator Placement

Evaluation of defibrillation threshold is a standard of care during implantation of implantable cardioverter defibrillator. High defibrillation thresholds are often encountered and pose a challenge to electrophysiologists to improve the defibrillation threshold. We describe a case series where defibrillation thresholds were improved after implanting a defibrillation lead in the azygos vein.
