Does device-based testing save time during automatic implantable cardioverter-defibrillator implantation? Indian Heart Journal. 2004 Jan-Feb; 56(1): 47-9http://imsear.searo.who.int/handle/123456789/3181BACKGROUND: Defibrillation testing can be done either via an external cardiac defibrillator or directly via the implanted defibrillator during implantation (device-based testing). The advantage of one testing methodology over the other has not been adequately studied. METHODS AND RESULTS: Seventy-four patients (72% men) were randomized into two groups depending on the defibrillation testing methodology used--external cardiac defibrillation and device-based testing groups. R-wave, pacing threshold, pacing impedance, defibrillation threshold, defibrillation pathway impedance and total procedure time were not significantly different between the two groups. CONCLUSIONS: Device-based testing did not significantly reduce the procedure time. Lead and defibrillation parameters were similar in both the groups; lead repositioning and replacement were required in three patients in the external cardiac defibrillation group.engAgedDefibrillators, ImplantableFemaleHumansMaleMaterials Testing --methodsMiddle AgedTime FactorsClinical Trial
