Key result
Stored electrogram retrieval from the Ventritex Cadence implantable cardioverter defibrillator enabled the troubleshooting of sensing lead failures in two patients.
Retrieval of stored electrograms from ICDs can be useful for troubleshooting sensing lead failures and inappropriate shocks.
Answers are grounded in this paper and cite their sources.
May aid ICD sensing troubleshooting in select cases; case reports leave broader utility hypothesis-generating.
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.
