Key result
The Gem DR dual chamber implantable defibrillator appropriately detected 100% of sustained ventricular tachyarrhythmias and reduced inappropriate detection of supraventricular tachyarrhythmias by 72%.
Why the study?
Does a dual chamber implantable cardioverter defibrillator safely and effectively detect ventricular tachyarrhythmias while reducing inappropriate detection of supraventricular tachyarrhythmias in patients requiring ICDs?

Does a dual chamber implantable cardioverter defibrillator safely and effectively detect ventricular tachyarrhythmias while reducing inappropriate detection of supraventricular tachyarrhythmias in patients requiring ICDs?
A dual chamber ICD with a discrimination algorithm safely and effectively detects ventricular tachyarrhythmias while significantly reducing inappropriate detection of supraventricular tachycardias.
Kühlkamp et al. (2002) conducted an observational in Ventricular tachycardia and sudden cardiac death survivorship (n=300). Dual chamber implantable cardioverter defibrillator (Gem DR) vs. Single chamber rate only detection was evaluated on Detection of sustained ventricular tachyarrhythmias. The Gem DR dual chamber implantable defibrillator appropriately detected 100% of sustained ventricular tachyarrhythmias and reduced inappropriate detection of supraventricular tachyarrhythmias by 72%.
