Is Defibrillation Testing Necessary for Implantable Transvenous Defibrillators?

[Is defibrillation testing necessary for implantable transvenous defibrillators].

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

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...

Implantable transvenous cardioverter-defibrillators.

BACKGROUND Implantable transvenous cardioverter-defibrillators offer a significant opportunity to decrease procedural morbidity and medical costs in the care of patients with life-threatening ventricular arrhythmias who otherwise would have required a sternotomy or thoracotomy for device insertion. The purpose of this study was to examine prospectively the safety, efficacy, and limitations asso...

Defibrillation Threshold for Implantable Defibrillators

Background The time constant of truncated exponential pulses used with implantable defibrillators is determined by the output capacitor size and defibrillation pathway resistance. The optimal capacitor size is unknown. Methods and Results This study compared defibrillation threshold (DFT) for standard 120-,uF capacitors (DFT120) and smaller 60-,gF capacitors (DFT60) at implantation of cardiover...
