Inappropriate implantable cardioverter defibrillator shocks secondary to sensing lead failure: utility of stored electrograms.
The Ventritex Cadence is a fourth generation implantable cardioverter defibrillator that provides for retrieval of stored electrograms related to therapy. In two patients, this feature enabled us to troubleshoot sensing lead problems, in one instance before it became clinically apparent. This may be an important consideration in selecting an appropriate device.
